Adult Stem Cell
Pluripotent stem cells can give rise to any fetal or adult cell type. However, alone they cannot develop into a fetal or adult animal because they lack the potential to contribute to extraembryonic tissue, such as the placenta.
Adult stem cells are the stem cells found in all tissues and fluids that are not embryonic.
Bone marrow from another individual results in rejection usually via graph vs. host disease. To prevent this rejection, the patient is treated with X-Rays and chemotherapy. This is done prior to the transfusion. This also results in the patient taking anti rejection drugs the rest of their life. Using one’s own adult stem cells does not produce a reaction/graph vs. host disease. This is autologous (self) stem cells from your body and prevents this rejection.
