ISSCA Opening of Uccle, Belgium Center with GCell & Stem Cell Training
After several months of organizing and developing a location, the Global Stem Cells Group has finalized the construction of a laboratory and regenerative medicine research center in Uccle, Belgium.
This facility serves both as a regenerative medicine treatment and research center, but also as a plastic surgery clinic. In addition to this, one of the primary goals of the Center is to serve as a place for the fostering of knowledge and experience regarding the different products and equipment required for the application of cellular therapies. As part of the inaugural ceremony a group of physicians were trained in the setup and use of the various regenerative medicine protocols and application process of these cells into the patients.
This center is a push into Europe for the Global Stem Cells Group. As the science advances, newer and more advanced therapies and technologies are being developed and released into the market with each passing month.
With the European Union being one of the largest consumer markets in the world, the finalization of a brick-and-mortar location in Brussels, Belgium is one that will mean great things for the Global Stem Cells Group, and the presence and proliferation of regenerative medicine throughout Europe and the world.
“This was a wonderful opportunity that we could have. It goes to show that even during this pandemic, the medical community is one that is still going strong. We’re still rallying together to look for new breakthroughs, and come up with the most beneficial treatment options for patients,” Said Benito Novas, founder of the International Society for Stem Cell Applications, “In addition to this, it also provides an excellent platform for the distribution of regenerative medicine therapies and equipment, including the revolutionary new GCell Machine,”
Indeed, the inaugural training at the Stem Cell Center in Uccle, Belgium was one that covered both of the more traditional methods of stem cell isolation and application– adipose and bone-marrow derived autologous cells, but this training was also one of the first in which the company had the ability to demonstrate the novel GCell Machine. Using a precise system of blades and filters, it is able to process a stem cell sample from adipose tissue in less than half of the time that it would take a physician to do so through traditional means.
This allows the patient to be more comfortable throughout the shorter procedure, as less anesthesia is also required than when operating under traditional means. The GCell is a minimally invasive, portable machine that allows physicians to fully unlock the potential of regenerative medicine as a component in their practice. Using their global network of distributors and licensed vendors, Global Stem Cells Group is working fervently to ensure no interruption in the global availability of the most cutting-edge regenerative medicine products.
Implications of Exosomes
As the newest field to regenerative medicine, it’s often exosomes therapy the least understood by those doctors newer to the field. While still not in use by many doctors, this is simply because it is new to the field. This is because many scientists are practically rabid to harnessthe benefits of this new treatment and apply them to target many of the conditions that modern medicine has allowed to slip through the cracks.
Extracellular Vesicles and Exosomes
The discovery of extracellular vesicles (EV), small bubbles composed of protein freely among cells, has been considered one of the greatest advancements in the field of medicine. They are broadly defined as something that exists outside of the cells of the human body, and they can be quite unique. Among these are exosomes, which has shown almost miraculous promise in treating inflammation, immunomodulation, cell-cell communication, and much more. Although it is certainly not a cure-all, it has been found to be good at what it does, which is almost a little bit of everything.This includes the communication and rejuvenation of all cells in the body, despite not actually being one itself.
Exosomes are created by growing a healthy stem cell culture and disposing of the cells themselves– this leaves behind the exosomes, millions of them, that were created in the process. Due to their microscopic size, what is left behind must be ultra-centrifuged, as it is the only way to concentrate them enough to use them on a patient. Despite all of their abilities, the makeup of exosomes is really quite simple, amino acids and RNA– this means that, aside from bearing immunomodulatory properties, it can also be applied to a patient without causing an immune system reaction. This is a worry that modern physicians must constantly think about when implanting foreign objects into patients, that is one of the great benefits of the use of exosome therapy.
An Overview on Exosome Therapy
Generally defined, exosome therapy is the use of exosomes in a clinical setting, a new step forward that is being happily taken by physicians worldwide. Exosome Therapy has very rapidly become one of the most popular fields of regenerative medicine treatment around the world. Painstaking research has managed to highlight the practical uses of exosomes, and how they can be used to treat conditions including lyme disease, hair loss, and arthritis. This is because, while stem cells are largely responsible for the rejuvenation of older cells, they might not be able to supply the information required for healing to take place– and this is where exosomes come in.
Consider exosomes the traffic conductors of regenerative medicine. They stimulate attention to damaged areas and work to control inflammation. In fact, many talented researchers believe that, by supporting the function of exosomes in the body, a better outcome could be obtained in patients. These scientific breakthroughs have fundamentally changed the healing process as we know it.
Exosome therapy is minimally invasive, and most commonly used in patients that present with orthopedic injuries, but this is not it’s only use. It shows great applications for anti-aging medicine, and the treatment of inflammatory and degenerative diseases. Exosome treatments generally contain a combination of growth factors, messenger RNA, micro RNA, and cytokines. The resulting exosome treatment is used in conjunction with stem cell therapies to boost the healing process in patients. These exosome therapies can be administered directly into the affected area, but they can also be administered through IV drip for those that are looking to make use of the anti-aging properties of exosomes.
Exosome injections are administered like other cellular therapies– administered directly into the part of the body affected by disease. In each case, patient dosing varies on condition and treatment plan, which means that there is no exact treatment protocol for exosome therapy. However, this allows physicians to fully customize them to a patient’s needs.
What can Exosomes Treat?
As the field of regenerative medicine constantly grows, more and more treatments are discovered every month! However, researchers have been able to offer exosomes as an exciting alternative for a wide variety of illnesses, including in arthritis therapy– it is believed to play a large role in bone and cartilage remodeling.Exosome therapy currently shows promise in treating the following conditions:
Hair Loss: Exosomes can be used to regrow hair due to their growth factor content. When injected exosomes trigger healing and the natural regeneration of hair follicles.
Lyme Disease: Exosomes may be beneficial to patients who suffer from Lyme disease, which is a very complex disease that compromises the immune system. Because it results in an increase in inflammatory responses, incorporating exosomes into one’s treatment plan could help break the cycle of inflammatory response.
Arthritis: Arthritis is known by many as the inflammation of the joints as a result of an autoimmune deficiency. Although various types of treatment are available to alleviate symptoms, nothing has been confirmed to reverse the disease’s progression.
Anti-Aging: Generally, aging can be thought of as a slow, steady inflammation of the body. Researchers have found a direct correlation between the number and types of exosomes within the body and the effects of aging, which means that exosome therapy could be used to reduce swelling in patients, and can be used to treat conditions such as crow’s feet, puffy eyes, and other markers of aging.
Pain Management: On a similar vein, many pain symptoms are also the result of inflammation– this is why certain over-the-counter medications allow for the treating of light pain. But for severe, chronic conditions that cannot be treated with over the counter options, exosome therapy could be the key to increasing their quality of life. By targeting the pained area at the source of inflammation, exosome therapy can increase quality of movement and reduce pain in certain orthopedic conditions including stress injuries.
As physicians around the world continue to study and apply exosomes, Global Stem Cells Group recognizes the fervent need to get these products into doctor’s hands. Our Cellgenic line has been in operation for years, helping physicians treat these conditions and more with exosome therapy.
Self-Care for Dummies
It is, quite frankly, impossible to use the internet in the twenty-first century without hearing much more than you want to about Self-Care. Most often, it is some sort of internet influencer telling you how important it is to take care of yourself, while plugging their sponsored products. However, and many of these people may be remiss to see someone say this, self-care doesn’t require a lot of money in the bank. Indeed, just a few simple lifestyle changes can be all you need to give you a new lease on life. With the world as chaotic as it is right now, it is vital to our mental (and, by extension, physical) health to practice self-care. Below, we’ve given you a rundown on what self-care is, and how it is surprisingly important to your overall well being.
What is Self-Care?
Put simply, self-care is being good to yourself and doing things that are good for you so that you feel better. Oftentimes, people do not have enough time in the day to consistently make the best choices possible. Other times, stress can get the better of them. It’s at these moments that it is important to take a step back, focus on our wellbeing, and make sure that we are taking care of ourselves. Self-care is not just about doing the things that you enjoy, it’s about doing the right thing. This means avoiding thighs that are unhealthy, including drugs, alcohol, or even toxic people– it’s caring for yourself like you would a friend in need.
Self-Care and Mental Health
If you feel like you’re far too stressed out, like the entire weight of the world is on your shoulders and you are unsure of how to live with the burden, can’t focus, and are starting to feel depressed, then it is likely that you are suffering from something known as mental exhaustion. So, how do you get a clearer head? Many people find that exercising is very good for this, as it brings endorphins into the brain and gets the heart pumping. For those who already exercise, but have similar problems with stress and mental focus, another option is meditation. Take 30 minutes each day to sit in a quiet room, close your eyes, and just focus on your thoughts while taking deep breaths. Meditation has been in use for thousands of years as a way to relieve some of the mental burdens that weigh us down.
Another thing that you can do is to take a break from social media or the internet. These days, people are bombarded with a constant barrage of information, whether it is advertisements, social media updates, news reports or app notifications. There’s way too much information out there, and our brains can’t handle it constantly. Reading a book before going to sleep is a great way to decompress– we all love TV, but books can stimulate our brain while allowing us to take it easy. If you are feeling overwhelmed, give your brain a noise from the constant noise and stimulus– mental health is important, and not something that should be taken for granted.
Self-Care and Physical Health
Taking care of your body is one of the cornerstones of self-care. If you are in good shape physically, and regularly exercise, it is very likely that your mind and spirit will be in as good a shape as your body. Living clean and caring for your physical health means cutting out fast food and junk foods, which are high in salt and sugar. These highly-processed products can mess with the brain, increase blood pressure, which can make you feel more anxious and stressed, and this is not even to mention the long-term effects hypertension can have on the health of your heart. When we are stressed, we gravitate towards the comfort foods that make us feel comfortable in the short term, those highly-processed, fatty foods that can wreak havoc on our bodies in the long term. After all, there was no such thing as a bag of chips in the Paleolithic era, and in terms of the processes of evolution the human body has not progressed far from cavemen. Put simply, humans were never meant to eat potato chips and hamburgers– that doesn’t mean you can’t of course, but it means that you should eat these foods in moderation.
It is important to eat healthy foods such as vegetables, nuts, fruits, whole grains, and lean meats. For the body, self-care also means exercise. You need to work out at least 45 minutes a day, 3-4 times a week. This will trigger the endorphins in your body, which help you to feel good and relax. Exercise is a great stress reliever, and it doesn’t need to be exclusively dumbbells, barbells, or other machines for heavy lifting. If you miss the gym days, however, I recommend combining IV drips with your routines to enhance both your performance and recovery.
Going for a walk outside among nature can also help with your mental health. You can also practice yoga, which emphasizes a balance between the three parts that exist within humans– the mind, the spirit, and the body. There are many great fitness routines and activities that you can choose from to help give your body the care that it needs.
Self-Care for the Soul
Emotional health is important as well. We often take for granted the emotions that we feel and, even more often, are unable to express them in ways that are healthy for us. Journaling is a good way to get in touch with what you are feeling. Expressing your thoughts and feelings on paper can give you some perspective on the situation, and help untangle what might feel like an impregnable wall of thoughts. Painting or drawing can also be a good release for your emotions, so is listening to music or, if you play an instrument, playing it yourself.
Reaching out to friends and family just to talk can also release some of the feeling you may have bottled up after weeks or months of not properly expressing them. If things are bad, you can also find a good therapist to assist you in talking about your problems. They can give you some strategies to change your thinking and feel better– whatever you decide, make sure not to bottle up your feelings, because eventually they will spill out. And this hardly ever ends well.
Other Self-Care Tips
Besides what we’ve mentioned above, we’ve created another blog post that contains more medically-oriented health tips for making sure that your body is operating properly. One important thing that you should do is to make sure that you are getting plenty of rest. A good night’s sleep is crucial, and most people require anywhere from 6-8 hours of sleep a night, but it varies from person to person, and some people might need more. Also, make sure that you are taking care of your hygiene as well. A long shower or bath could be just what you need to melt the stress of the day’s work away and leave you feeling refreshed and renewed. Make sure to avoid alcohol or drugs when dealing with stress, however– they will only make the problem worse. You can also drink herbal teas to help you relax and fortify your immune system, which has been found to be weaker when the body is stressed.
Really, you just need to remember to be good to yourself– treat yourself like a friend, and be kind. We are often our own worst enemies, and while this is mostly used in professional and social settings, it is also true when caring for yourself. After all, it is you who allows yourself to indulge in your worst impulses. Try to focus on your best impulses and taking care of yourself when you need it, and you’ll feel the difference.

Healthy Skin and You: How to Subtract Years from Your Face
Those people who are younger and have never had to face any of the effects of aging firsthand, often have a naive view of getting older– that they will age like fine wine. But in reality, the human body ages more like a fine milk. And this is because, well, we are alive! As the years take their toll, many people find that skin is one of the places that suffers the most as youthful vigor fades away into middle age. Having healthy skin takes a bit of work, and with the wide variety of anti-aging products, treatments, and nutrients that are available both over the counter and through clinical consultations, learning how to take care of your skin can seem like a bit of a daunting task. That’s why we’re here to help! All you need to do is keep a few basic things in mind, and you’ll be on the fast track to younger-looking, healthier skin.
Moisturized Skin is Happy Skin
This might be the simplest tip that there is, and is really the foundation for healthy skin: moisturizing! You must have heard it before, from any variety of sources, and if you haven’t– well, consider this your wakeup call. The skin is the largest organ in the human body, and it is one of the only outwardly-facing ones that there are– because of this, the skin is one of the organs that is most susceptible to damage, and you can think of moisturizer as a shield that can protect and preserve the quality of your skin.
The main use of moisturizers, in a medical sense, is to protect the skin from environmental exposure. This environmental exposure can be present in many ways, from the Sun’s UV rays, to hot showers, to exceedingly cold air– what do these things all have in common? They wear the skin down by causing it to dry out, causing cracks and wrinkles. When we apply moisturizer, it helps to hold water onto the surface of the skin, and draws water deeper into its layers. Hydrated skin looks younger, fuller, and often, more wrinkle-free, but there’s more! The right moisturizer will also serve to help the skin in repairing itself (this is often because it is fortified with certain vitamins), and can also stimulate blood circulation, which is another way to ensure that your skin looks healthy.
Next time you’re shopping for moisturizer, take a look at the ingredients on the back of the label before you apply them to your face. The best anti-aging moisturizers contain vitamins A, B5, C, or E, but it is also important to find a moisturizer that also includes SPF, especially if you live in sunnier climates.
Water, The Liver, & The Skin — A Skincare Cycle
In addition to hydrating the surface of your skin, it is important to hydrate the whole body! Staying hydrated is very important for healthy skin, and, by extension, so is the health of your liver. It is safe to say that having a healthy liver means that your skin will be similarly healthy.
Everything that we eat and drink, whether it is water or rice and beans, is processed in our livers. The liver is the greatest asset the body has to detox it, and it can at times be useful to consider it to be the garbage disposal of the body. After all the nutrients have been used, the liver disposes of the leftovers– and when the liver is dehydrated, it has been found to be significantly less effective in flushing out waste (lack of hydration impacting performance is a trend that can actually be seen all throughout the organs and systems of the human body). When the liver is not working at one-hundred percent, the body often decides to use different routes for detoxification, and one of the first ones is the skin. When the liver isn’t functioning well, people are more likely to experience skin irritation and blemishes like acne.
Stress and Cortisol Management
There’s a decent chance you didn’t expect stress to be on this list. It’s true that when I began researching this topic, I was a bit dubious about stress’ major impact on skin health, but there is no way to refute evidence– and keeping your stress in check has been found to be just as important as moisturizing.
It’s been found to be true that some people break out with rashes or acne when they are stressed. What’s more, people that have rosacea or eczema might find that their condition flares up when they are feeling stressed out. The reality is that there are a number of factors that contribute to this unfortunate correlation. Firstly, stress causes the body to release more cortisol (commonly known as the ‘stress hormone’), which makes the skin oily, clogs the pores, and causes breakouts. The next is that stress can also negatively affect the proteins in the skin, making it harder to retain water and elasticity. Dry skin that is not elastic has a higher chance of developing cracks or wrinkles, and– even worse, perhaps, stress has been found to interrupt a good night’s sleep, which leads to bags under the eyes and often a terrible feeling of sluggishness.
So, how can we reduce stress? That’s largely easier said than done, as many people certainly already know. There are, however, a few things that you can do that might help to wind you down:
- Exercising
- Practicing Self-Care
- Enjoy Relaxing HObbies
- Connect With Friends and Family
- Meditate
- Express your Feelings
- Speak to A Therapist
Nutrition and the Skin
People often say that you are what you eat, but that is not entirely accurate. It’s probably a bit more accurate to simply say that you are as healthy as the food that you put into your body– this means that if all you are putting into your body is over-processed food with little to no real nutritional value, your skin (and energy, and immune system, and digestive system– everything,really), is going to take a major hit.
One of the most important things that you need to consider specifically for skin health is the presence of antioxidants in food that you eat. Antioxidants help fight off the damage that is caused by free radicals that harm the skin cells, making them one of the most powerful anti-aging tools available. Vitamin C, E, and A are rich in antioxidants and are found in food like strawberries, oranges, nuts, spinach, broccoli, fish, and dairy products. When possible, try to go organic, and we also recommend including a nutrient-rich vitamin IV drip into your routine– it is one of the least invasive ways to ensure that your body has an overabundance of the building blocks it needs to function well.
Similarly, bad nutrition leads to bad skin. Refined carbs like white bread, pastries, candy, and corn syrup, cause glycation, a major factor in premature aging.
The Importance of Humidity
We talked plenty about moisturizers, but there is another important tool that you can use to keep your skin hydrated and healthy, especially if you live in colder climates. It is known as a humidifier– when most people think of one, they get the association with being sick, and this is for good reason. After all, humidifiers are one of the most tried and true methods for reducing sinus inflammation, but they also have a positive effect on the skin.
Dry air strips the skin of oils and makes it easier for our faces to get irritated. Putting a humidifier in the areas of your home that you use the most is a simple, but effective, way of keeping your skin looking happy and healthy.
In Conclusion
When we treat ourselves well, our body rewards us with younger, healthier-looking skin. Looking for more ways to rejuvenate your skin? Check out our facial care services to give yourself a youthful glow.

How to Check-In on Your Health
Many people say that health is wealth– and this is because, really, many people do not know how important and crucial their health is until a certain part of their body is suffering– at which point they realize that they took their health for granted. However, just like checking your bank statements to verify where your money is being spent, there are several easy ways that you can keep an eye on your health yourself. If you are really concerned, and there might be something seriously wrong with you, a visit to a hospital or clinic might be necessary, but otherwise, there are a few things that you can do right at home if all you need is a simple check. In fact, you’d be surprised at just what you can find out about yourself with just a few simple tests.
Check Your Temperature
One of the easiest ways to simply check on your general health is to take your own temperature. All you need is a digital thermometer, which can be found at nearly any pharmacy, and place it under your tongue for a few moments until it beeps to get a reading. From there, you have an accurate gauge at how ‘hard’ your body is working– the higher the body temperature, the more energy that the body is using.
This could be due to a variety of reasons, including illness or exercise, and the baseline temperature for the majority of people is around 98.6. Any temperature over or under that number (even by a few tenths of a degree) can be cause for concern. If you’d prefer not to put one in your mouth, they make thermometers for the ears, as well as digital forehead scanners– whatever method you’d prefer, it is important to try and invest in a good thermometer, so that you can get as accurate a reading as possible.
Blood Pressure
If someone was to ask you what your blood pressure was today, would you be able to even give them a ballpark estimate? While many people do not know exactly what it is, even fewer recognize just how important this metric of bodily function is. High blood pressure, also medically known as hypertension, is one of the leading causes of heart disease– it can be caused from eating lots of salty foods, smoking, or drinking. Additionally, it can also depend on a variety of other internal factors including age, race, family history, and your amount of exercise.
A blood pressure that is too high can lead to many major health problems aside from heart disease. It can also cause heart attacks, strokes, heart failure, and can affect the health of the brain as well. A good investment to check blood pressure is a blood pressure cuff– they make electronic ones, which are a bit more expensive, and old-fashioned ones that you blow up yourself by squeezing. In any case, it is important to know that a healthy blood pressure reading is around 120/80– anything higher would be a cause for concern, and a reason to consult with a medical professional.
Checking Your Pulse
Checking your pulse, or heart rate, is a simple test that doesn’t require any special equipment. In fact, it is something that people have been doing much the same way for centuries! It is very important to know your resting heart rate, as those with a higher average resting heart rate tend to be more at risk for heart disease than those with a lower heart rate (this is simply because the heart works more), and heart disease remains the leading cause of death in the United States of America.
So, how do you check your pulse? All you need to do is take your index and middle finger and place them on your neck by your Adam’s apple. Then, count your heartbeat for a full 60 seconds, and you’re done! Congratulations, you’ve successfully discovered your resting heart rate. The average pulse is somewhere between 70-100 beats per minute, or bpm. If it is lower than that, it means that you are in good shape, and if it is higher, it means you are not. It costs absolutely nothing to check your pulse and get a rough estimate of the health of your heart.
Alternatively, as technology continues its relentless march forward, you can use your smartphone or smartwatch to get a quick read of your pulse. Certain devices, such as Galaxy phones and the iWatch come with a built-in heartbeat sensor that can also monitor stress levels.
How to Measure your Waist
All you need for this is a tape measure, or to look at your pants size. The size of your waist is positively correlated with your weight. To measure it with a tape measure (as, depending on the fit of your pants, it may be the most accurate measure) all you need to do is take the end of the tape measure and bring it around your waist. Tighten it, and you should be able to measure the circumference of the waist. Healthy men are expected to have a waste smaller than 40 in, while women should have a waist lower than 35.
There is no problem with accepting your weight the way it is, but part of accepting it means accepting the fact that being overweight makes you more susceptible for a wide range of health risks.
Check for Lumps
This is extremely important, and should be done regularly throughout your life. If you are a woman, you should be regularly checking your breasts for any lumps. This should be done in front of a mirror, as it can often provide a better view. To do this, all you need to do is work your way from the armpits to the nipple and check for any bruises, lumps, or discoloration– in short, anything that looks like it might not belong there. It can be done in as little as five minutes, but it is extremely important and one of the cornerstones to good health. If you find anything that is unusual, the earlier you catch it before it becomes a problem, the better. If you are a man, it is important to examine the testicles in a similar way. Feel around the sack and put a little pressure on the testes to feel for anything unusual. It may feel awkward, but it is far better to be safe than sorry with such a thing.
How Skin Plays into Health
The sun is something that everyone experiences every single day– at least, we should hope so, but this is not always a good thing. It’s warm, comforting rays can actually make human beings more susceptible to skin cancer. It’s important to put sunscreen on, at least 50 SPF before leaving the house every day. If you want to check your skin at home, you can, but there’s a few simple things that you have to keep in mind. Stand Stand in front of a mirror and examine every part of your body. You might want to have someone there to help you in examining your back– you want to look for warning signs that are known as the “ABCDE” Signs.
A is for asymmetrical shape, B is for irregular borders, C is for abnormal color, D is for diameter, and E is for evolving. If a mole is larger than a pencil in diameter, has a weird color, is not an even circle, or changes appearance over time, you should head over to a dermatologist as soon as possible.
These are just a few of the things that you can do at home to check up on your health. It is important to check your health regularly so that you can catch any strange developments early on– Invest in some equipment like thermometers and blood pressure monitors– they don’t have to break the bank, but they do have to be accurate. This is one way that you can keep an eye on your health, to hopefully catch any problems you might have before it’s too late to do so.

Blood plasma reduces symptoms and fatalities in outbreaks of coronavirus.
The US blood donation centers are making unarguable efforts to collect plasma from COVID-19 patients who have recovered from the disease. They are hoping to use it to save the life of those who are still infected with this disease.
According to the guidelines released on Tuesday by AABB, an international nonprofit agency focused on transfusion medicine and cellular therapies, many community blood centers located nationwide could be an important source for this Old treatment method known as Convalescent plasma therapy.
In this treatment method, Blood products are taking from patients who survived this viral disease, and it’s been injected into those that are still infected. This experimental practice has a history of been used in the 1930s to treat measles. In the 1918s, during the disastrous flu, recently, this plasma therapy has been used to treat those infected with H1N1 influenza, SARS and Ebola.
Clinical researches have shown that the use of plasma offers some hope and reduces symptoms and fatalities in past outbreaks of coronavirus.
In the recent surge of COVID-19, unproven evidence from china has shown that passive antibody treatment has helped COVID-19 patients until they were able to develop their natural antibodies that can fight off the disease.
This procedure is a promising one to try given that there’s no treatment or vaccine for COVID-19, experts say.
“There’s nothing else out there,” said Dr. Louis Katz, an expert in the blood industry, leading the AABB’s working group on Convalescent plasma.
The new guidelines were made a week later after the Federal Food and Drug Administration authorized the immediate use of Convalescent plasma by doctors for critically ill COVID-19 patients.
The first medical center to use this therapy is the Houston Methodist Hospital, and they have been able to treat two COVID-19 patients since Saturday, says a spokesman. The results are pending.
The New York blood center and some other sites have begun the collection of plasma since last week from patients who have recovered from this pandemic infection, and a few clinical trials have started to test this convalescent plasma for COVID-19. The American Red Cross has organized a site to collect information about potential plasma donors.
As the AABB join the effort with America’s Blood Centers, a new rollout could develop the practice exponentially, said Katz.
“This is all the medicine on the fly, right?” we don’t have the randomized controlled trials. We’re going to do our best that we can,” said Katz.
At community blood centers, the plasma will be collected from COVID-19 survivor donors with a lab-confirmed test; these donors must have tested negative and stopped experiencing symptoms for over 28days, according to the guidelines.
Several research laboratories and medical companies are trying effortlessly to detect the antibodies that fight the virus. It may be hard for some blood centers to access the test at first, says Katz.
Meanwhile, centers will be allowed to collect plasma from COVID-19 survivor donors, and it will be administered to “Critically ill patient as quickly a possible” and then test for antibody titers later, Said the FDA spokesman on Tuesday.
This will make a great difference in the potential amount of plasma collected from COVID-19 survivors. Said Katz. “We can go the whole hog, now that we have such an accommodating stance from the agency”, he also said.
Felberbaum noted that an emergency investigational new drug or e-IND, authorization is required to transfuse convalescent plasma into patients, but not to distribute it after collecting it from the donor. According to him, the FDA has granted “numerous” requests for emergency INDs and continues to grant them as they are received.
Seattle-area blood center, Bloodworks Northwest, is working effortlessly with the National institutes of health and the University of Washington to start harvesting plasma from victims who have recovered from COVID-19. These donations will become a part of a research study co-led by a professor of medicine, Dr. Terry Gernsheimer, at UW school of medicine. They will also be recorded in a national registry being created to track the result of the plasma therapy, says Dr. Rebecca Haley, a medical director of Bloodworks Bio that produces biological products.
There is a high expectancy of interest among those who have suffered through the global infection.
Dr. Jon Peters is a 66 years old family practice physician in Portland who is also a victim of the Pandemic infection. Although he’s at home and still experiencing symptoms, he plans to donate plasma and get back to work as soon as his symptoms subside and once he’s able to do so.
There is a very low-risk issue or complication for the donor but could be a lifesaver to someone out there, he said.
It is good to know that “at this point, they require every option they can get” hence, this therapy can offer a solution to this ravenous pandemic.

What is Exosome therapy?
Exosomes are extracellular vesicles (that’s particles that release naturally from a cell that cannot replicate) that are responsible for certain genetic information, otherwise known as Exosomes cell to cell communication. They transport molecules that are essential regulators of intracellular information between close and distant cells.
Exosomes play a vital role in the communication and rejuvenation of all the cells in our body. Despite not being a cell, Exosome has proven to be quite important in maintaining a healthy cellular terrain.
Exosomes are typically made by growing stem cells in culture. Taking the media where they grow and then getting rid of the stem cells. Due to the small size of Exosomes, the media is then ultra-centrifuged to concentrate the exosomes.
Exosomes contain different molecular constituents of their cell origin; these include proteins and RNA. Meanwhile, the Exosomal proteins composition varies with the cell and tissue of the origin; most Exsomes contains an evolutionarily conserved common set of protein molecules.
HOW TO ISOLATE EXOSOME FROM CULTURE STEM?
Exosomes can be isolated from culture stem cell using the method Ultracentrifugation. Often combined with sucrose density gradients, they float the relatively low-density Exosomes from other microvesicles. Cells and larger particles are removed by sequentially increasing the centrifugal forces. These procedures can take up to 30hours and requires an ultracentrifuge, extensive training and specialized equipment.
This method provides highly enriched exosomes but requires specialized training and equipment.
Now, this is how Exosomes works:
Exosomes carry genetic information. Protein and messenger RNA, they can relay this information, letting cells know when to and how to react. This Exosomes cell-to-cell communication is possible due to its unique shape and content.
Exosomes from young stem cells rejuvenate the older cells and assist in calming an overreactive immune system or modulating it to respond in a coordinated and more effective fashion.
WHAT IS EXOSOME THERAPY?
Exosome therapy is one of the hottest areas of regenerative medicine treatment. Researchers have given us valuable insight into the practical functionality of exosomes. While stem cells are usually responsible for the rejuvenation of older cells, they may not be able to supply all the information needed. So supporting Exosome function could have a greater positive effect, by providing a new piece of information to enhance the healing process.
Exosome therapy is a minimally invasive procedure commonly used in orthopedic injuries, for anti-aging and some other degenerative diseases. Exosomes treatment contains growth factors, messenger RNA, micro RNA, cytokines and other biologically active molecules in conjunction with stem cell therapy to speed up healing benefit.
Exosome therapy can be injected into the affected area like in orthopedic injuries or given intravenously for anti-aging.
This Exosome injection is administered directly into the affected area, and the dosing for every patient varies, and there is no set protocol.
Exosomes treatment is gaining popularity recently, due to its ability to transfer molecules from one cell to another via membrane vesicle, therefore influencing the immune system, such as dendrite cells and B cells.
What is exosome therapy used for?
HAIR LOSS: Exosomes injection can be used to regrow hair loss due to its growth factor content. When injected, Exosome will trigger healing, cell stimulation and natural regeneration of these hair follicles. Exosome hair loss therapy is cutting-edge in hair restoration. According to research, there is a positive relationship between Exosomes and Hair loss. Exosomes are ideal for people with thinning hair, excessive shedding or hair loss proper. This is because Exosomes are regenerative cells that can heal, repair, stimulate and restore cells and tissues.
LYME DISEASE: Exosomes may help to regulate processes in the body, and may also be beneficial to patients with Lyme disease. Lyme disease is a very complex disease, which compromises the immune system. Many Lyme patients suffer from dysfunction of the mast cells, increasing their inflammatory response and metabolic function. Incorporating Exosomes treatment in their treatment regimen may help break the inflammatory response and provide the body with necessary cellular information to facilitate healing.
ARTHRITIS: Arthritis as we all know, is the joint inflammation resulting from an autoimmune disease. Although various types of treatment are available to alleviate symptoms, no known therapy has been confirmed effective in reversing the disease progression.
In the field of regenerative medicine today, with the discovery of extracellular microvesicles, especially exosomes, many researchers have been able to offer a more exciting alternative on this subject matter. Exosome arthritis therapy is believed to play a more substantial role in bone and cartilage remodeling.
In a nutshell, Exosomes provides enormous potential in the field of regenerative medicine. You can advance your understanding of Exosomes and its relationship with stem cell in this course. This is an online-course https://www.cellulartherapycourse.com/ where physicians and medical personnel can get insight and deep understanding of this novel science (Exosome).

How to boost your immune system to fight cancer?
The human immune system helps to protect the body against illness and infection caused by bacteria, viruses, fungi, and parasites. This process is achieved by a collection of reactions and responses made by the body to damage these infected cells. It is also called immune responses.
This immune system is very crucial in cancer patients to help fight cancer, it dictates this cancer as abnormal and destroys it, but this is not enough to rid of cancer altogether. In most cases, cancer will weaken this immune system because it will spread into the bone marrow that produces blood cells that fights against infections and cause the bone marrow to decrease in its blood cell production.
When this immune system is unable to recognize these cells as abnormal, cellular growth will occur, causing uncontrolled growth and division of cells, that will, in turn, lead to cancer.
Cancer has been a serious and sensitive talk for both patients and doctors. Being diagnosed with cancer is frightening and tormenting, but due to the latest treatment method, recovering from this disease is increasingly possible. Living with cancer often brings an initial psychological crisis, but surprisingly it does not only affect you but your family and others close to you.
Cancers, especially genetic cancer can’t be prevented, so it is essential to be proactive about your health. If you’re diagnosed with cancer, some individual lifestyles that will help improve your cancer care, which includes managing stress. Reducing your stress level can help you to maintain physical and mental stress; you can use relaxation techniques such as meditation and yoga. Getting enough sleep is also crucial for patients living with cancer; this will help improve their health, mood, and coping ability. Also, it is best the limit their exposure to toxins that can increase one’s risk of being exposed to other deadly diseases.
A healthy feeding habit is critically important and can help manage cancer side effects, improve health, and quick recovery. Some tips to help you develop a good and healthy feeding diet include:
- Consuming assorted types of vegetables in all your meals. Vegetables are essential and should not just be a side dish but the centerpiece of your meal.
- Consuming foods rich in fiber like grains, beans, peas, nuts, and seeds.
- Consuming less red meat, like pork, lamb, goat, and bison.
- The presence of probiotic and prebiotic foods helps to support a healthy gut. Probiotic foods include yogurt or other fermented vegetables, and prebiotic foods include raw or cooked onions, dandelion greens, and legumes.
- Avoid processed and canned foods
- Avoid foods high in calories and low in nutrients like fruit-flavored drinks, sodas, candies, and sweets.
- Lastly, cut down on the excessive intake of alcohol.
Some other routines can help improve cancer care like regular exercise. Regular exercise helps to control fatigue, muscle tension, and anxiety in those with cancer, and it is essential, especially during and after cancer treatment, so keep fit and avoid adding unnecessary weight.
CANCER TREATMENT
There are many cancer treatment options for different types of cancers. Cancer treatments depend on the type and how to advance it is. Some patients with cancer will only have one treatment option, while others will end up with a combination of more that one treatments technique depending on the type and stage of cancer.
Curing cancer is one of the significant challenges of the 21st century. However, few advances to tame the immune system are getting closer to a future where cancer can be a curable disease.
Although cancer treatment is dependent on the stage and type, we need a wide range of therapies that work on cellular level like NK cell and stem cell therapies, wide enough to cover the whole spectrum of cancer. Cancer therapies involving the immune system is believed to be a milestone for cancer treatment advances, and the development of multiple immune cells as a therapeutic tool.
Our knowledge of cancer has dramatically improved in recent years. And it seems increasingly evident that there has been a surge of new technologies, and these technologies could make a great impact on the way we treat cancer, taking us closer to finally curing this deadly disease.
One of these promising cancer treatment advances is the natural killer (NK) cell-based immunotherapy.
NK CELLS
Natural killer cells have emerged as the newest promising therapeutic approach to cancer. Our understanding of the biological processes that take place in cancer is increasing rapidly, leading to this new type of targeted treatment and therapeutic approach. It is hard to overstate the possible importance of NK cells in the future of cancer. Modern researches have shown that NK cells are a type of treatment that stimulates a persons’ immune system to fight cancer, and this may give room for a greater number of chances to beat cancer for good. NK cells are also known for their ability to target cancer stem cells making these cancer stem cells visible to the immune system.
NK cells was first identified in the 1970s as a unique lymphocyte subset that can recognize and kill abnormal cells without prior sensitization of specific tumor antigen, thus preventing the growth of many cancers. During the late 1980s, something was observed, and this was that NK cells could destroy a lymphoma cell line that had lost MHC class I surface molecules while the original MHC class I+ cells were resistant to lysis, which led to the formation of the “missing self-hypothesis” which states that NK cells can sense the absence of “self” MHC class-I molecule on target cells. In recent years, the hypothesis was confirmed by the inhibitory and activating NK cell receptors.
This discovery indicates that autologous cells are not killed by NK cells, thanks to an appropriate expression of all self-HLA alleles, do not kill an autologous cell. In contrast, a wide spec of cancer types can be killed due to the loss of HLA molecules and to the expression/overexpression of ligands for NK cell activating receptors.
Now, this is how NK therapy works
NK cells firsts recognize the tumor cells via stress or danger signals from their sensors.
Then, the Activated NK cells directly decimate the target tumor cells through at least four mechanisms. These mechanisms are cytoplasmic granule release, death receptor-induced apoptosis, effector molecule production, or ADCC.
Furthermore, NK cells act as regulatory cells when reciprocally interact with DCs to improve their antigen uptake and presentation. This action helps in facilitating the generation of antigen-specific CTL responses that is vital in dictating foreign invasion and tumor cells.
Also, by producing cytokines such as IFN-γ, activated NK cells induce CD8+ T cells to become CTLs. Activated NK cells can also help in the differentiation of CD4+ T cells toward a Th1 response and promote CTL differentiation. Cytokines produced by NK cells might even have the unique ability to regulate antitumor cells, making them more proactive.
Accordingly, The cytokine gene transfer approach induces NK cell proliferation, and this increases survival capacity. Further enhancing their activation and also making them more potent in malignant cell multiplication dictation.
The NK cell scientist has assured that by using NK cell lines, modifying genes such as IL-2, IL-12, IL-15, and stem cell factor (SCF). They have been demonstrated the ability of the NK to restore their cytotoxic capacity as well as increase their proliferative rate, survival ability, and in vivo antitumor activity. However, the specificity of NK cells is still limited, and studies are even passing through phases. The approach focuses on retargeting NK cells to tumor cells by gene transfer of chimeric tumor-antigen specific receptors.
NK therapy is promising research; it raises the prospect of “one-end-solution” to many different types of cancers across the Globe. If the studies and experiments work out pretty well, the NK cells will be able to increase the activity of CD4+, CD19, and other important disease-fighting cells of the body.
There is no doubt that this an unimaginable feat, both in advancing our basic knowledge about regenerative medicine and for the possibility of future cancer treatment advances.

Can Stem Cells treatment Regrow the knee cartilage?
Some people believe that stem cell does all of this but studies have shown that It’s unlikely only in a few unique cases. You can observe minimal growth a year after the patient took treatment, but this doesn’t mean replacement of the cartilage.
The cartilage has a reduced regenerative capacity, and current and present pharmacological medications only offer symptomatic pain relief. Osteoarthritis patients that respond poorly to conventional therapies are ultimately treated with surgical procedures to promote cartilage repair by implantation of artificial joint structures (arthroplasty) or total joint replacement (TJR). Surgery has been the last resort for serious cartilage problems.
In the last two decades, stem cells derived from various tissues with varying differentiation and tissue regeneration potential have been used for the treatment of osteoarthritis, damage to bones and others either alone or in combination with natural or synthetic scaffolds. The stem cells derived from these tissues primarily aid cartilage repair. Although stem cells can be differentiated into chondrocytes in vitro or aid cartilage regeneration in vivo, their potential for Osteoarthritis management remains limited as cartilage regenerated by stem cells fails to fully recapitulate the structural and biomechanical properties of the native tissue. It isn’t easy for the cartilage to regrow and assume its original biomechanical and structure form.
Apparently, Due to the limited intrinsic capacity of resident chondrocytes to regrow the lost cartilage post-injury, stem cell-based therapies have been proposed as a novel therapeutic approach for cartilage repair.
Also, stem cell-based therapies using mesenchyme stem cells (MSCs) or induced pluripotent stem cells (iPSCs) have been used successfully in clinical and preclinical situations.
Part of the issues associated with Mesenchyme stem cells can be averted by using iPSCs. iPSCs are an ideal patient-specific unlimited cell source for autologous tissue regeneration. With the Promising in vitro; studies have shown that vitro results have already been demonstrated in the cartilage engineering field for iPSCs. These were generated from various cell types.
What Is Cartilage and How Does It Get Damaged?
Cartilage is a connective tissue in the human body and body of other animals. In our joints, we have a few kinds of cartilage, but most often people refer to the smooth lining of a joint called articular or hyaline cartilage. This kind of cartilage gives rise to a soft layer of cushion on the end of a bone at the joint. The cushion is essential for balance, mechanical functions and athletics. This tissue of the cartilage is very strong, yet it can compress, readjust and absorb varying degrees of energy. It is also very slippery, smooth and flexible and these features allow the joint to glide effortlessly through a broad range of physical motions of any kind.
When joint cartilage is not working correctly or damaged, this smooth-cushioning-layer can be worn away, and this becomes a problem. In the case of traumatic injuries, sometimes a sudden force causes the cartilage to break off or poorly become damaged, exposing the underlying bone of the body. In the case of osteoarthritis (also called degenerative/wear-and-tear arthritis), over time that smooth layer can wear thin and uneven. Aging can also cause the cartilage to break off and certain life factors and diseases too, e.g. autoimmune diseases.
Eventually, as that cushion of the bones wears away, joint movements can become inflexible, stiff and painful on one or both legs (bones). Joints can even become inflamed and swollen. And as all these conditions, typically causes pain and limitations in activity become problematic. The action or activities that involve these bones leads to crushing pain and discomfort, depending on the severity of the case. Almost all activities involve the movement of bones; hence this condition is not an easy one.
There are some treatments for cartilage damage and arthritis. Although there some medicines, most of these treatments are focused either on relieving symptoms by smoothing down the damaged cartilage or concentrate on replacing the joint surface with an artificial implant. The later is for end-stage conditions, and the artificial plane is procedures such as knee replacement or hip replacement surgery.
How Can Stem Cells Help?
Stem cells are specialized cells that can multiply reform and develop into different types of tissue. In the developmental stages of a fetus, stem cells are plentiful and surplus. However, in adulthood, stem cells are restricted to specific tasks of regenerating a few types of cells, such as blood cells and liver cells in some cases of damage. There are almost no stem cells found in cartilage tissue, and therefore there is little to no capacity to heal or regrow new cartilage. For adults, the ability to regrow new cartilage is even more difficult due to age and lack of stem cells in the cartilages.
Most often, in the setting of orthopedic surgery and joint problems, stem cells are obtained from adult stem cell sources. The primary sources are bone marrow and fatty tissue. These stem cells can develop into cartilage cells, called chondrocytes.
They also exhibit some other helpful qualities by stimulating the body to reduce inflammation, stimulate cell repair, and improve blood flow. This process is caused by the secretion of cellular signals and growth factors to stimulate the body to initiate healing processes.
Once stem cells have been obtained, they need to be delivered to the area of the cartilage that damaged. One option is to inject the stem cells into the joint. There have been many studies investigating just this, and some data shows improvement in symptoms. How much of this improvement is the result of new cartilage growth versus other effects of stem cells (the healing properties listed above, including the anti-inflammatory effects) is unknown.
There is a challenge with giving stem cell injection. The problem with just injecting stem cells is that cartilage is a complex tissue that is comprised of more than only cells hence this can pose a challenge because the stem can’t regenerate all the things in the cartilage.
To regrow the cartilage, the complex tissue structure and biomechanics of cartilage must also be reconstructed to its former status. Cartilage can often /described as having a scaffold-like structure that is composed of water, cells, collagen, and proteoglycans, and infection-fighting antibodies. Injecting just the stem cells is thought to be less effective in stimulating the formation of the entire cartilage structure hence the challenge.
Some studies are investigating the types of 3-dimensional tissue scaffolds engineered to have a cartilage-like structure. The stem can then be injected into the scaffold, in hopes of better restoring a healthy type of cartilage. Three-dimensional printing is becoming an exciting part of this type of research. If everything works out as expected, the cartilage reconstruction could be achieved to a very high percentage.
How do stem cells work?
Necessarily, stem cells are progenitor cells which are capable of regeneration and differentiation into a wide range of specialized cell types. Once injected, stem cells follow inflammatory signals from damaged tissues and have multiple ways of repairing these damaged areas. It works as though the part is developing new; like what is seen during a child’s development.
The mesenchyme stem cells (MSCs) we are using are considered to be multipotent (they can transform into different cell types but cannot form an organ) but not pluripotent. In the body, these cells Do NOT function by transforming into different cell types or tissues.
They act via anti-inflammatory activity, immune modulating capacity, and the ability to stimulate regeneration. We go through a very high thorough screening process to find cells that we know have the best anti-inflammatory activity, the best immune modulating capacity, and the best ability to stimulate regeneration process on the tissue with damage.

Although the expectation on this stem cell course is yet to be achieved; however, this is a part of medicine that can offer one-end-solution to various bone and body problems.
With the recent high-tech studies, efforts and dynamics, stem cell treatment can be a breakthrough in the future as its perspectives are very promising and unique. It is also not dangerous on the long-run.

Clinical trials on NK cells give hope for many people Who are suffering from cancer.
Induced pluripotent stem cells (also known as iPS cells or iPSCs) are a type of pluripotent stem cell that can be generated directly from a somatic cell. Pluripotent stem cells hold promise in the field of regenerative medicine. Because they can propagate indefinitely, as well as give rise to every other cell type in the body (such as neurons, heart, pancreatic, and liver cells), they represent a single source of cells that could be used to replace those lost to damage or disease.
Natural killer cells are the type of cytotoxic lymphocyte critical to the innate immune system. The role NK cells play is analogous to that of cytotoxic T cells in the vertebrate adaptive immune response. NK cells provide rapid responses to virus-infected cells, acting at around three days after infection, and respond to tumor formation.
Typically, immune cells detect the major histocompatibility complex (MHC) presented on infected cell surfaces, triggering cytokine release, causing apoptosis. NK cells are unique, however, as they can recognize stressed cells in the absence of antibodies and MHC, allowing for a much faster immune reaction.
Clinical Trial on NK cells
In a first clinical trial, a natural killer cell immunotherapy derived from induced pluripotent stem cells is being tested for safety in 64 patients with a variety of solid tumors. The first subjects used for the study received the cells in February at the University of California, San Diego (UCSD) Moores Cancer Center and MD Anderson Cancer Center.
This study is targeting late-stage cancer patients with solid tumors, including lymphoma, colorectal cancer, and breast cancer. The FT500 NK cells do not undergo any further alterations and after their derivation from the induced pluripotent stem cells (iPSCs), offering the possibility of a quicker, ready-made treatment.
Human embryonic stem cells induced iPSCs
Human embryonic stem cells (hESCs) and induced pluripotent stem cells (iPSCs) provide an accessible, genetically tractable, and homogenous starting cell population to efficiently study human blood cell development. These cell populations provide platforms to develop new cell-based therapies to treat both malignant and nonmalignant hematological diseases.
The NK cells are immune cells in the same family as T and B cells and are very good at targeting cancer cells for destruction. Some Laboratory experiments have shown they do so by attacking cells that have lost their significant self-recognition signals that tell the immune system not to attack. This is the phenomenon that can happen among cancer cells but not to healthy cells. Experts are not sure how many cancer cells lose that signal. Researchers are hopeful that the clinical trial can help determine which cancer patients could benefit the most from NK cell treatment.
iPS Clone
The ability to induce pluripotent stem cells from committed, human somatic cells provides tremendous potential for regenerative medicine. However, there is a defined neoplastic potential inherent to such reprogramming that must be understood and may offer a model for critical understanding events in the formation of the tumor. Using genome-wide assays, we identify cancer-related epigenetic abnormalities that arise early during reprogramming and persist in induced pluripotent stem cell (iPS) clones. These include hundreds of abnormal gene silencing events, patterns of aberrant responses to epigenetic-modifying drugs resembling those for cancer cells, and presence in iPS and partially reprogrammed cells of cancer-specific gene promoter DNA methylation alterations.
Progress in adoptive T-cell therapy for cancer and infectious diseases is hampered by the lack of readily available antigen-specific, human T lymphocytes. Pluripotent stem cells could provide an estimable source of T lymphocytes, but the therapeutic potential of human pluripotent stem cell-derived lymphoid cells generated to date remains uncertain.
Modification of T cells
Recently, some Approved cell therapies for Cancer also rely on modifying T cells, in those cases to produce cancer cell–binding chimeric antigen receptors (CARs), and have been effective in treating certain cancers such as leukemia.
Application of CAR T-Cell Therapy in Solid tumours
The Car T technology has wowed the field by all but obliterating some patients’ blood cancers, but solid malignancies present new challenges.
Therapies that contains such chimeric antigen receptor (CAR) T cells have been approved for some types of so-called liquid cancers of the blood and bone marrow, large B-cell lymphoma and B-cell acute lymphoblastic leukemia. But the approach has not had as much success for solid tumors.
Serious research into the therapy for brain cancer started almost 20 years ago after cancer biologist WaldemarDebinski, then at Penn State, discovered that the receptor for the immune signaling molecule interleukin 13 (IL-13) was present on glioblastomas, but not on healthy brain tissue. The receptor thus seemed like an excellent target to home in on cancer cells while sparing healthy ones. The CAR spacer domain that spans the immune cells’ membranes and its intracellular co-stimulatory areas, as well as the process used to expand cells outside the body, to boost the T cells’ activity.
CAR T- A Safer Cell Therapy
While managing CAR T-cell therapy toxicity could help keep already-designed treatments on their march to the clinic, many immunotherapy companies are also working to develop a new generation of inherently safer therapies, yet just as efficient. A crucial part of achieving this goal will be improving CAR specificity for target cells. With current treatments, the destruction of normal cells is often an unavoidable side effect when healthy tissue carries the same antigens as tumors; noncancerous B cells, for example, are usually casualties in CD19-targeted therapies.
CAR T delivery is a non-easy factor in the treatment of solid tumors and other unknown forms of tumors. With the non-solid cancers, cells are administered by a blood infusion, and once in circulation, the CAR T can seek out and destroy the rogue cells. For solid tumors, it’s not so simple.
The main drawback of taking cells from a patient and developing them into a cellular immunotherapy product is that the process can take weeks.
Patel tells The Scientist “But for the majority of patients who may not be a candidate or may not have time to wait for such an approach, the idea that there’s off-the-shelf immunotherapy that could potentially as a living drug act against their cancer, I think is a fascinating concept,”
