The ontogeny of mullerian inhibiting substance in granulosa cells of the bovine ovarian follicle.
Mullerian Inhibiting Substance (MIS) previously detected in the Sertoli cells of the calf testis has been localized in the granulosa cells of the ovarian Graafian follicle by using an immunoperoxidase technique and a monoclonal antibody (IG8) to MIS that almost completely blocks its biological activity. The immunoperoxidase technique (avidin-biotin complex method) demonstrated specific localization of MIS in the cytoplasm of the ovarian granulosa cells in the bovine Graafian follicles over a wide age span, i.e. one day, one week, three months, two-and-a-half years and five years. The presence of MIS in the ovary implies a function that is as yet unknown.
