Illustration of stem cells. Stem cells can differentiate into any other cell type. There are three main types of mammalian stem cell: embryonic stem cells,derived from blastocysts; adult stem cells,which are found in some adult tissues; and cord blood stem cells,which are found in the umbilical cord. The type of cell they mature into depends upon the biochemical signals received by the immature cells | |
