Stem cells are a class of undifferentiated cells that are able to differentiate into specialized cell types. Commonly, stem cells come from two main sources:  -Embryos formed during the blastocyst phase of embryological development (embryonic stem cells)  -Adult tissue (adult stem cells)  Both types are generally characterized by their potency, or potential to differentiate into different cell types (such as skin, muscle, bone, etc.).
