Naïve and primed pluripotent stem cells resemble epiblast cells of the pre-implantation and post-implantation embryo, respectively. This chapter describes a simple experimental system for the efficient and consistent transition of human pluripotent stem cells (hPSCs) from the naïve to the primed state, which is a process called capacitation. Naïve hPSCs after capacitation can be differentiated further to somatic lineages, thus reproducing the order of developmental events in the embryo. Protocols for the induction of neuroectoderm, definitive endoderm, and paraxial mesoderm from hPSCs after capacitation and also from conventionally derived primed hPSCs are included in the chapter. Importantly, hPSC capacitation closely recapitulates transcriptional, metabolic, signaling, and cell polarity changes in the epiblast of primate embryos, and therefore offers a unique in vitro model of human peri-implantation development.
