Cellular Distribution of Transforming Growth Factor Betas 1, 2, and 3 and their Types I and II Receptors during Postnatal Development and Spermatogenesis in the Boar Testis1

Abstract excerpt

Transforming growth factor betas (TGF betas) 1, 2, and 3 and their types I and II receptors (TGF betas RI and RII) were immunolocalized 1) during testicular development from the perinatal to the adult period and 2) in maturing germ cell populations at successive seminiferous epithelium stages. In the perinatal testis, TGF beta isoforms and receptors were both preponderant in Leydig cells and in spermatogonia. At...
