Human embryonic (hESCs) and induced pluripotent stem cells (hiPSCs) have been shown to differentiate into primordial germ cells (PGCs) but not into spermatogonia nor haploid spermatocytes or spermatids. Here we show that hESCs and hiPSCs differentiate directly into advanced male germ cell lineages including post-meiotic, spermatid-like cells in vitro without genetic manipulation. Furthermore, our procedure mirrors spermatogenesis in vivo by differentiating pluripotent stem cells into UTF1, PLZF and CDH1-positive spermatogonia-like cells, HIWI and HILI-positive spermatocyte-like cells, and haploid cells expressing acrosin, transition protein 1 and protamine 1, proteins found uniquely in either spermatids and/or sperm. These spermatids show uniparental genomic imprints similar to human sperm on two loci: H19 and IGF2. These results demonstrate that male pluripotent stem cells have the capability to directly differentiate into advanced germ cell lineages and may represent a novel strategy for studying spermatogenesis in vitro.
