Prepubertal human spermatogonia and mouse gonocytes share conserved gene expression of germline stem cell regulatory molecules
14 Dec 2009
Abstract excerpt
In the human testis, beginning at approximately 2 months of age, gonocytes are replaced by adult dark (Ad) and pale (Ap) spermatogonia that make up the spermatogonial stem cell (SSC) pool. In mice, the SSC pool arises from gonocytes approximately 6 days after birth. During puberty in both species, complete spermatogenesis is established by cells that differentiate from SSCs. Essentially pure populations of...
