The Homeobox Transcription Factor RHOX10 Drives Mouse Spermatogonial Stem Cell Establishment.

ABSTRACT: The developmental origins of most adult stem cells are poorly understood. Here, we report the identification of a transcription factor-RHOX10-critical for the initial establishment of spermatogonial stem cells (SSCs). Conditional loss of the entire 33-gene X-linked homeobox gene cluster that includes Rhox10 causes progressive spermatogenic decline, a phenotype indistinguishable from that caused by loss of only Rhox10. We demonstrate that this phenotype results from dramatically reduced SSC generation. By using a battery of approaches, including single-cell-RNA sequencing (scRNA-seq) analysis, we show that Rhox10 drives SSC generation by promoting pro-spermatogonia differentiation. Rhox10 also regulates batteries of migration genes and promotes the migration of pro-spermatogonia into the SS
