Evidence for a FSH dependent secretion of a receptor reactive transforming growth factor beta-like material by immature Sertoli cells in primary culture.
Type beta Transforming Growth Factor (TGF beta)-like activity was identified in conditioned medium obtained from immature porcine Sertoli cell-enriched cultures using the following criteria: (i) stimulation of anchorage independent growth of mesenchymal cell lines, (ii) competition with pure human TGF beta in a radioreceptor assay. The secretion of the receptor reactive TGF beta-like material in Sertoli cell conditioned medium is decreased to very low or undetectable levels by Follicle Stimulating Hormone, one of the major hormones involved in the physiological testicular activities. The effects of this factor are probably exerted in the context of the local control of the male gonad functions.
