Scientists have been studying stem cells for decades, and many of their findings, all pretty remarkable, aren’t widely circulated. Periodically, we will share one of these stem cell research breakthroughs here on this blog. Summary: The skin renews, heals wounds, and regenerates the hair that covers it thanks to a small group of stem cells.
The human brain, as it turns out, is far more malleable than we once thought. Even adult brains. But they are subject to age-related diseases and disorders, such as dementia and diminished cognitive function. There is hope that medical science may be able to replace brain cells and restore memory in aging patients thanks to
Researchers at the University of Toronto have developed a tracer ink—a “stem cell tattoo”—that provides the ability to monitor stem cells in unprecedented detail after they’re injected. The research findings, titled “Bifunctional Magnetic Silica Nanoparticles for Highly Efficient Human Stem Cell Labeling,” was published in June in the Journal of Magnetic Resonance Imaging. Already emerging as
Researchers from Harvard University and the University of Nottingham have developed a new filling that stimulates stem cells in dental pulp to regenerate and even regrow teeth damaged by disease and decay. According to Newsweek Magazine, the discovery earned a prize from the Royal Society of Chemistry after judges described it as a “new paradigm
Stem cell research has never been more advanced, and as a result many different types of treatments are currently offered on the market. Unfortunate ly, some providers are practicing quackery in stem cell therapies, and an abundance of well-intentioned scientific and medical personnel are prematurely publicizing their work. These providers and publishers have cast an
Chronic lung diseases are the third leading causes of death in the U.S. Chronic lung diseases include a collection of illnesses that cause airflow blockage and breathing-related issues, including primarily chronic obstructive pulmonary disease (COPD), bronchitis, emphysema and asthma. Lung disease involves changes in cells within the lungs, and while research on lung stem cell
An adult stem cell is an undifferentiated cell, found among differentiated cells in tissue or an organ. The adult stem cell can renew itself and can differentiate to yield some or all of the major specialized cell types of the tissue or organ. The primary role of adult stem cells in a living organism is to maintain and repair
The most important resource on stem cell clinical trials is registry ClinicalTrials.gov. This registry provides the public with easy access to information on publicly and privately supported clinical studies. The ClinicalTrials.gov web site is maintained by the National Library of Medicine at the National Institutes of Health. Information (NIH) and is provided and updated by the
What are the potential uses of human stem cells? What obstacles must still be overcome before these potential uses will be realized?
There are many ways in which human stem cells can be used in research and in the clinic. Studies of stem cells continue to yield information about their complex capabilities. A primary goal of this research is to identify how undifferentiated stem cells become the differentiated cells that form the tissues and organs. Scientists know that turning genes on
Researchers are learning about mending a broken heart–that is, how to generate healthy heart muscle stem cells in the laboratory and then transplant those cells into patients with chronic heart disease. Preliminary research in mice and other animals indicates that bone marrow stromal cells, transplanted into a damaged heart, can have beneficial effects. Whether these cells can
The difference between stem cell research and therapy is in the scientific evidence that supports therapeutic intervention to be beneficial for the patient. Stem cells have the remarkable potential to develop into many different types of cells in the body during early life and growth. In addition, in many tissues, stem cells serve as a sort
The term stem cell research gleans different reactions from people, both in the medical community and the wider public. Still an emerging science, stem cell research is shrouded by many myths and misconceptions. Here, we take on some of the most predominant myths to discuss the misconceptions and clarify the facts regarding this fast-growing branch
