SUMMARY Specification of primordial germ cells (PGCs) marks the beginning of the totipotent state. However, without a tractable experimental model, the mechanism of human PGC (hPGC) specification remains unclear. Here we demonstrate specification of hPGC-like cells (hPGCLCs) from germline competent pluripotent stem cells. The characteristics of hPGCLCs are consistent with the embryonic hPGCs and a germline seminoma that share a CD38 cell surface marker, which collectively defines likely progression of the early human germline. Remarkably, SOX17 is the key regulator of hPGC-like fate, while BLIMP1 represses endodermal and other somatic genes during specification of hPGCLCs. Notable mechanistic differences between mouse and human PGC specification could be attributed to their divergent embryonic development and pluripotent states, which might affect other early cell fate decisions. We have established a foundation for future studies on resetting of the epigenome in hPGCLCs and hPGCs, for totipotency and the transmission of genetic and epigenetic information.

- A Unique Gene Regulatory Network Resets the Human Germline Epigenome for Development (2015, methodology): “Following upregulation of SOX17 and BLIMP1, maintenance and de novo DNA methylation pathways are repressed in hPGCLCs, whereas 5hmC is globally enriched with upregulation of TET1 (Irie et al., 2015).”
