 are cells found in most, if not all, multi-cellular organisms. A common example of a stem cell is the Hematopoietic stem cell (HSC) which are multipotent stem cells that give rise to cells of the blood lineage. In contrast to multipotent stem cells, embryonic stem cells are pluripotent and are thought to be able to give rise to all cells of the body. Embryonic stem cells were isolated in mice in 1981, and in humans in 1998.
