Identification and characterization of repopulating spermatogonial stem cells from the adult human testis

Abstract

This study clearly demonstrates that repopulating human SSCs have phenotypic characteristics of SSEA-4(+), CD49f(+), GPR-125(+)and c-Kit (neg/low). The results have direct implications for enrichment of human spermatogonia for further culture and germ cell differentiation studies.
