Anytime you are dealing with human or animal tissue, there is the danger of infection or the spreading of disease. In Spain they have been working on this issue for years and there is a paper by Fernando Cobo of the Stem Cell Bank of Andalucía in which he addresses this issue. Here is a small portion:
“Regenerative medicine therapies will allow in the future the transplant of cells of human origin in some diseases that until now have been incurable. The assurance of the safety and quality, especially from a microbiological point of view, is very important for these therapeutic products.
Depending on the starting material, there are several sources of pathogen presence, mainly human viruses. Also, the use of feeders of animal origin as layers in which the stem cells can grow may permit the transmission of animal pathogens to these cells. However, cell sources are limited due to the low availability of spare in vitro fecundation human embryos and the low rate of success in the derivation of human stem cell lines. Thus, in several cases, it will be necessary to evaluate the possibility of removing or inactivating these microorganisms.”
In the paper titled “Application of methods for viral clearance in stem cell production,” Cobo summarize the main methods of viral clearance and we have provided an overview of the main features taking into account in the viral clearance techniques.
Here is a quick overview from a group of scientists in Massachusetts (Beth Israel Deaconess Medical Center and University of Mass Medical School) explaining how they were able to derive “immortal” stem cells from human hair follicles: _____________________________________ Multi-potentiality of a new immortalized epithelial stem cell line derived from human hair follicles By: Cecilia Roha, … Continue reading
Stem cells reside in all areas of the body. At one time, scientists believed that stem cells only resided in the bone marrow. Science has taught us differently now. Stem cells reside in the skin. The stem cells here are responsible for holding off the signs of aging and damage. Let’s face it, we all … Continue reading
Many people ask why we even need stem cells for regeneration. After all, if stem cells are being harvested from the human body for therapy, why are our own stem cells not working to ward off disease or aging? This is a very good question. Everyone assumes that a stem cell is a perfect cell, … Continue reading
Fetal stem cells have been another source of controversy through the years. Some people disagree with using a fetus for stem cell research. Several factors are involved in the controversy. Aborted fetuses, via abortion, were used at one time for a source of fetal stem cells. Unplanned miscarriages are another source. These avenues evokes many … Continue reading
Have you ever wondered how stem cells injected into the body know precisely where to go in the body for healing and regeneration? Here is an abstract from Giselle Chamberlain, et al, from Leopold Muller Arthritis Research Centre, School of Medicine, Keele University, Robert Jones and Agnes Hunt Orthopaedic Hospital, Oswestry, Shrops, United Kingdom. The … Continue reading
Many people hear the term stem cell, but rarely understand what a stem cell is. Usually jargon used in the stem cell research field is muddled with scientific vocabularly that leaves the average person wondering what the researchers had just said. This paper, outlining the mechanisms of a stem cell in an unusual work of … Continue reading
People find that many new therapies promoted in the press or by their doctors as the next great silver bullet, does not live up to the hype and may be downright quackery. These sensationalist claims are intended to pull more money out of your wallet with the promise of the next biggest and greatest invention … Continue reading
Adult Stem cells, the little amazing (re)creation cells, have been shown to become dysfunctional when exposed to radiation. The reason this research paper is so interesting is because of the amount of radiation we are exposed to every day from airport scanners, to actually flying in the air, to wifi, computers, cell phones, and GPS … Continue reading
When many people hear the words stem cells they often think of cloning or babies being created or killed for science. Stem cell research really doesn’t have anything to do with cloning. That is a separate science altogether. Fetuses from abortions were used in stem cells therapies. However, this avenue proved to be unreliable. Unassisted, … Continue reading
