Adult stem cells are undifferentiated cells found throughout the body after embryonic development that divide to replenish dying cells and regenerate damaged tissues . Also known as somatic (from Greek Σωματικóς, of the body) stem cells , they can be found in children, as well as adults.

Adult stem cells, similar to embryonic stem cells, have the ability to differentiate into more than one cell type, but unlike embryonic stem cells they are often restricted to certain lineages. The ability of a stem cell of one lineage to become another lineage is called transdifferentiation . Pluripotent stem cells can be found in a number of tissues including umbilical cord blood.[7] Using genetic reprogramming, pluripotent stem cells equivalent to embryonic stem cells have been derived from human adult skin tissue.
