The primary role of adult stem cells in humans is to maintain and repair the tissue in which they are found. Stem cells are very flexible cells, sometimes considered immature, that have not developed to a final specialized cell type like skin, liver, heart, etc. Since they have not yet specialized, stem cells can respond to different signals and needs in the body by becoming any of the various cell types needed, e. In that sense they are a bit like a maintenance crew that keeps repairing and replacing damaged or worn out cells in the body. Microscopic in size, stem cells are big news in medical and science circles because they can be used to replace or even heal damaged tissues and cells in the body. They can serve as a built-in repair system for the human body, replenishing other cells as long as a person is still alive.

Adult stem cell

Currently, blood stem cells are the only type of adult stem cell used regularly for treatment; they have been used since the late s in the procedure now commonly known as bone marrow transplant. Transplants of neural stem cells have been tried in small numbers of patients with brain disorders such as Parkinson disease, and the FDA recently approved a clinical trial of neural stem cells for spinal cord injury. Preliminary research in animals has found that bone marrow stromal cells, injected into a damaged heart, can have beneficial effects. In some cases, it may be possible to infuse the stem cells into the blood, as in a bone marrow transplant.
