Confusions About Totipotency: Stem Cells Are Not Embryos (Updated)

Dr. Maureen Condic explains why reprogrammed stem cells are not embryos – an “organism” is organized.

Totipotent zygotes are distinct from pluripotent or even plenipotent stem cells because they undergo development. The ability to both produce all cell types and to organize them into a coherent body plan is the defining feature of a totipotent human organism.
