Definition

Adult stem cells are multipotent and can differentiate into several types of tissues. They are synonymic to precursor or progenitor cells. It is generally assumed that these cells are already genetically committed to a certain cell type. Adult stem cells occur in various tissues of the adult body, and have the physiologic function to be able to regenerate some tissues which obey a strong degradation. For example, the hemotopoietic stem cells regenerate blood and immunologic cells since they are quickly degraded.
