Project description:Human testis development in prenatal life involves complex changes in germline and somatic cell identity. To better understand, we profiled and analyzed ~32,500 single-cell transcriptomes of testicular cells from embryonic, fetal and infant stages. Our data shows that at 6-7 weeks post-fertilization as the testicular cords are established, the Sertoli and interstitial cells originate from a common heterogeneous progenitor pool, which then resolves into fetal Sertoli cells (expressing tube-forming genes) or interstitial cells (including Leydig-lineage cells expressing steroidogenesis genes). Almost ten weeks later, beginning at 15-16 weeks post-fertilization, the male primordial germ cells exit mitosis, downregulate pluripotent transcription factors and transition into cells that strongly resemble the ‘State 0’ spermatogonia originally defined in the infant and adult testes. Therefore, we termed these fetal spermatogonia ‘State f0’. Taken together, we reveal multiple insights into the coordinated and temporal development of the embryonic, fetal and postnatal male germline together with the somatic niche.

Project description:Human adult spermatogenesis involves a balance of spermatogonial stem cell self renewal and differentiation, alongside complex germline-niche interactions. To better understand, we performed single cell RNA sequencing of ~7000 testis cells from three healthy men of peak reproductive age. Our analyses revealed multiple distinctive transcriptional ‘states’ of self-renewing and differentiating spermatogonia, the cellular stages of gametogenesis, five niche cells (Leydig, Myoid, Sertoli, Endothelial, macrophage) and insights into germline-niche communication. Spermatogenesis was reconstructed computationally, which identified sequential coding, noncoding, and repeat-element transcriptional signatures. A new, developmentally early and likely quiescent spermatogonial state is identified (GFRA1-/ETV5-/ID4+/UTF1+/FGFR3+). Notably, certain epigenetic features combined with nascent transcription analyses suggest considerable plasticity within certain spermatogonial populations/states. Key findings were validated via RNA and protein staining. Taken together, we provided the first “Cell Atlas” of the adult human testis, and provide multiple new insights into germ cell development and germ cell – niche interaction.

Project description:Unhealthy aging of testis seriously affects fertility and life quality of older men, while its interventions depend on in-depth knowledge of the molecular and functional changes of various testicular cell types. Here, we profile human testicular single-cell transcriptomes from young adult, healthy old men and late-onset hypogonadism (LOH) patients, and identified the somatic cells underwent a greater change than germ cells.
