ABSTRACT Insulin-like growth factor-I (IGF-I) enhances and epidermal growth factor (EGF) inhibits gonadotrophin-induced aromatization in granulosa cells. Our previous studies have shown that human ovarian granulosa cells synthesize insulin-like growth factor-binding protein-1 (IGFBP-1) which inhibits IGF-stimulated DNA synthesis. The present study addresses the effect of EGF and gonadotrophins in the regulation of IGFBP-1 release by human granulosa cells cultured in serum-free medium. At concentrations of 1–100 μg/l EGF was found to stimulate IGFBP-1 secretion. This was not due to cell proliferation, as the viable cell count remained unaffected. Growth hormone and gonadotrophins had no effect on IGFBP-1 secretion when added alone to culture medium. These results suggest that EGF regulates IGFBP-1 secretion in human granulosa-luteal cells.
