Regulation of gap junctions and oocyte maturational competence by gonadotropin and insulin-like growth factor-I in ovarian follicles of red seabream.

The in vitro effects of human chorionic gonadotropin (hCG) and human insulin-like growth factor-I (IGF-I) on the formation of oocyte-granulosa cell (heterologous) and granulosa cell-granulosa cell (homologous) gap junctions (GJ) were determined during the course of development of oocyte maturational competence (OMC) in ovarian follicles of red seabream… CONTINUE READING
