THYROID HORMONE AS A REGULATOR OF BASAL AND HUMAN CHORIONIC GONADOTROPHIN-STIMULATED STEROIDOGENESIS BY CULTURED PORCINE THECA AND GRANULOSA CELLS ISOLATED AT DIFFERENT STAGES OF THE FOLLICULAR PHASE

摘要

To characterize thyroid hormone action in the ovary, the direct effect of triiodothyronine (T-3) was investigated in vitro using a culture system of porcine theca cells (Tcs) and granulosa cells (Gcs) in mono- and co-culture (GT), the latter resembling follicles in vivo.
