摘要: In vitro induction of functional haploid cells from embryonic stem (ESCs) has been reported by several groups. However, these reports either involve complex process with undefined factors or show low-induction efficiency. Here, we report complete meiosis in ESCs defined factors. were first induced into primordial germ cell-like cells, which further male germline including spermatogonial (SSCLCs) and spermatid-like cells. Importantly, the obtained SSCLCs as infertile mice sired healthy offspring via SSCLC transplantation. Further, found that eukaryotic translation initiation factor 2 subunit 3 structural gene Y-linked (Eif2s3y) was essential for spermatogenesis. Eif2s3y-overexpressing showed enhanced spermatogenesis vitro, demonstrated higher expression levels SSC-specific markers during process, improved reproductive ability recovery mice, increased efficiency cell induction. Our work provides a convenient efficient approach to obtain
