Source of Cells
Research into the effectiveness of adult stem cells has generated excitement in recent years. Slightly more mature adult stem cells are undifferentiated cells, found in organs and tissue throughout the adult body, such as bone marrow, brain tissue, skin, teeth, liver, gut, and the heart. In short, adult stem cells come from the patient and not an external source. Evidence suggests that these cells compose on the outer layer of small blood cells and remain in a prolonged, non-divided state until the body activates them in response to injury or disease.
