Effect of adrenergic agonists on human chorionic gonadotropin release by human trophoblast cells obtained from first trimester placenta.

Abstract

The cultured syncytiotrophoblast cells from human first trimester placenta were used to determine the effect of adrenergic agonists on human chorionic gonadotropin (hCG) production in vitro. Beta-adrenergic agonists isoproterenol, ritodrine and isoxsuprine increased the hCG release during the 2 h incubation period, however, alpha-agonists norepinephrine and… (More)
