What is stem cell therapy?
Stem-cell therapy is the use of stem cells to treat or prevent a disease or condition. As of 2016. [update] , the only established therapy using stem cells is hematopoietic stem cell transplantation. This usually takes the form of a bone-marrow transplantation, but the cells can also be derived from umbilical cord blood.
Why are stem cells being studied?
Stem cells are being studied for a number of reasons. The molecules and exosomes released from stem cells are also being studied in an effort to make medications. In addition to the functions of the cells themselves, paracrine soluble factors produced by stem cells, known as the stem cell secretome, have been found to be another mechanism by which stem cell-based therapies mediate their effects in degenerative, autoimmune, and inflammatory diseases.
How many discrepancies were found in 2013 studies of autologous bone marrow stem cells on ventricular
In 2013, studies of autologous bone-marrow stem cells on ventricular function were found to contain "hundreds" of discrepancies. Critics report that of 48 reports, just five underlying trials seemed to be used, and that in many cases whether they were randomized or merely observational accepter-versus-rejecter, was contradictory between reports of the same trial. One pair of reports of identical baseline characteristics and final results, was presented in two publications as, respectively, a 578-patient randomized trial and as a 391-subject observational study. Other reports required (impossible) negative standard deviations in subsets of people, or contained fractional subjects, negative NYHA classes. Overall, many more people were reported as having receiving stem cells in trials, than the number of stem cells processed in the hospital's laboratory during that time. A university investigation, closed in 2012 without reporting, was reopened in July 2013.
How to regenerate tissue in adult?
A possible method for tissue regeneration in adults is to place adult stem cell "seeds" inside a tissue bed "soil" in a wound bed and allow the stem cells to stimulate differentiation in the tissue bed cells. This method elicits a regenerative response more similar to fetal wound-healing than adult scar tissue formation.
What are the effects of stem cells on animal models of brain degeneration?
Research has been conducted on the effects of stem cells on animal models of brain degeneration, such as in Parkinson's disease, Amyotrophic lateral sclerosis, and Alzheimer's disease. Preliminary studies related to multiple sclerosis have been conducted.
How do corneal stem cells help restore vision?
Since 2003, researchers have successfully transplanted corneal stem cells into damaged eyes to restore vision. "Sheets of retinal cells used by the team are harvested from aborted fetuses, which some people find objectionable." When these sheets are transplanted over the damaged cornea, the stem cells stimulate renewed repair, eventually restore vision. The latest such development was in June 2005, when researchers at the Queen Victoria Hospital of Sussex, England were able to restore the sight of forty people using the same technique. The group, led by Sheraz Daya, was able to successfully use adult stem cells obtained from the patient, a relative, or even a cadaver. Further rounds of trials are ongoing.
