Cripto is one of the key regulators of embryonic stem cells (ESCs) differentiation into cardiomyocites vs neuronal fate. Cripto−/− murine ESCs have been utilized to investigate the molecular mechanisms underlying early events of mammalian lineage differentiation. 2D/LC−MS/MS and a label-free LC−MS approaches were used to qualitatively and quantitatively profile the cripto−/− ESC proteome, providing an integral view of the alterations induced in stem cell functions by deleting the cripto gene.
