Figure 2From: Norepinephrine stimulates progesterone production in highly estrogenic bovine granulosa cells cultured under serum-free, chemically defined conditionsEstradiol, progesterone, and pregnenolone production by bovine granulosa cells. Time-effect on production of estradiol (A), progesterone (B), and pregnenolone (ng/ml) (C) by bovine granulosa cells cultivated under chemically defined conditions supplemented with PVA. Values are least square means ± SEM (n=7 independent cultures). a, b unlike superscripts differ P<0.05.Back to article page
