Totipotency is the absence of any developmental restriction, a feature naturally found in the early embryo right after fertilization. Generating an in vitro totipotent stem cell model is not a trivial task. For this reason, a set of stringent criteria for the identification of bona fide totipotent stem cells have been proposed.
