Detailed explanation-1: -The two defining characteristics of a stem cell are perpetual self-renewal and the ability to differentiate into a specialized adult cell type.
Detailed explanation-2: -Stem cell therapies have been used to treat autoimmune, inflammatory, neurological, orthopedic conditions, and traumatic injuries, with studies conducted on use for Crohn’s disease, Multiple Sclerosis, Lupus, COPD, Parkinson’s, ALS, Stroke recovery, and more.
Detailed explanation-3: -Stem cells originate from two main sources: adult body tissues and embryos. Scientists are also working on ways to develop stem cells from other cells, using genetic “reprogramming” techniques.
Detailed explanation-4: -Stem cells are different from other cells in the body in three ways: They can divide and renew themselves over a long time. They are unspecialized, so they cannot do specific functions in the body. They have the potential to become specialized cells, such as muscle cells, blood cells, and brain cells.
