Pluripotent Stem Cells in the Early Embryo

Stem cells serve as the source of all the other specialized cells in the body. Here is part 2 of a series of four animations on stem cells created by Riken CDB to highlight some of the basic biological properties of stem cells, explain the different types of stem cell found in the embryonic body and the adult and illustrate the roles of these "master cells" in development and regeneration.
