Mammalian spermatogenesis is a complex, highly productive process generating millions of sperm per day. Spermatogonial stem cells (SSCs) are at the foundation of spermatogenesis and can either self-renew, producing more SSCs, or differentiate to eventually produce sperm. This unique ability of SSCs renders them a promising tool in developing therapies for the treatment of male infertility. However, difficulties in unequivocally identifying human SSCs (hSSCs) and complexity in replicating their functions in vitro have hampered our understanding of hSSCs and our ability to utilize them for assisted reproductive technologies. This study employed single-cell RNA sequencing (scRNA-seq), immunohistochemistry, flow cytometry, xenotransplantation, and cell culture techniques to molecularly characterize putative human hSSCs. Identifying the protein markers of hSSCs and the signaling pathways regulating their self-renewal and proliferation will facilitate the development of efficient, effective, and safe SSC-based therapies to treat male infertility.
