   Stem cells are cells found in all multi-cellular organisms. They were isolated in mice in 1981, and in humans in 1998. [1] In humans there are many types of stem cells, each with varying levels of potency. Potency is a measure of a cell's differentiation potential, or the number of other cell types that can be made from that stem cell.
