title: A novel maturation marker for human Sertoli cells.
abstract: The maturation of Sertoli cells at puberty is critical for the initiation and maintenance of spermatogenesis. Little is known about the factors which control Sertoli cell maturation. We have examined Sertoli cells in testicular specimens from 44 subjects, ranging in age from 6 months to 67 years, for reactivity with a mouse monoclonal antibody (M2A) using the immunoperoxidase reaction. We found positive reactivity with prepubertal but not postpubertal Sertoli cells, suggesting that the antigen defined by M2A was a marker of immature Sertoli cells. This marker may be useful for studying the factors which influence Sertoli cell maturation during development of the testis.
