Factors inducing epithelial to mesenchymal transition, such as the transcriptional repressor Snail1, have been implicated in cancer stem cell development and function. Here Lin et al.report that endogenous Snail1 is not required for embryonic stem cell pluripotency and self-renewal, but rather regulates Wnt-induced epiblast differentiation.
