Germline-soma segregation is a fundamental event during mammalian embryonic development. Here we establish the epigenetic principles of human primordial germ cell (hPGC) development using in vivo hPGC
PIWI-clade Argonaute proteins silence transposon expression in animal gonads. Their target specificity is defined by bound ~23-30nt piRNAs that are processed from single-stranded precursor transcripts
Background: Spermatogonial stem cells (SSCs) sustain the process of steady-state spermatogenesis in the mammalian testis, which is critical to the ongoing production of sperm and male fertility. SSCs
