Describe some applications of stem cells.
Stem cells have wide-ranging applications in medical science. The primary goal of stem cell therapy is to repair damaged tissues that cannot heal themselves. A notable successful application is bone marrow transplantation, which is already in clinical use.
Stem cells show promise for treating various diseases including muscle damage, cancer, Huntington's disease, Type 1 diabetes mellitus, Parkinson's disease, cardiac failure, celiac disease, and neurological disorders. In eye disease treatments, improved vision has been observed with transplantation of retinal pigment epithelial cells derived from embryonic stem cells.
For wound healing and skin replacement, skin (keratinocyte) stem cells from hair follicles can be cultured to develop skin equivalents for patients. This offers faster healing for skin injuries, genetic disorders, and burnt wounds with lower inflammation. Stem cells also help study genetic defects, understand disease causes, and test new lead molecules as drugs.
