Figure 3From: Norepinephrine stimulates progesterone production in highly estrogenic bovine granulosa cells cultured under serum-free, chemically defined conditionsPropranolol effect on norepinephrine-induced progesterone production. Effect of propranolol on norepinephrine-induced progesterone production (ng/ml) in highly estrogenic bovine granulosa cells cultivated under chemically defined conditions supplemented with PVA for 48h. Values are least square means ± SEM (n=5 independent cultures). a, b unlike superscripts differ P<0.05.Back to article page
