Sertoli-spermatogenic cell co-cultures prepared from sexually immature rats (20–22 days old) and maintained in serum-free, hormone/growth factor-supplemented medium were used to determine the cell-specific localization of the growth factor somatomedin-C (SM-C). SM-C localization studies were carried out by indirect immunofluorescence using a monoclonal antibody (sm-1.2) to SM-C. In cultured rat hepatocytes, Sertoli and testicular peritubular cells, SM-C immunoreactivity was observed as a diffuse distribution of discrete immunofluorescent granules. Radio-immunoassay experiments using a rabbit antibody against human SM-C showed that testicular peritubular cells and Sertoli cells in primary culture accumulated SM-C in the medium. In spermatogenic cells co-cultured with subjacent Sertoli cells, immunoreactive SM-C was associated with pachytene spermatocytes but not with spermatogonia or early meiotic prophase spermatocytes (leptotene or zygotene). Both Sertoli cells and pachytene spermatocytes displayed binding sites for exogenously added SM-C. SM-C6 binding to spermatocytes reaching an advanced stage of meiotic prophase suggests a possible role of this growth factor in the meiotic process.
