placental lactogen

(Science: chemical) A polypeptide hormone secreted by the placenta that enters the maternal circulation and disappears from the circulation immediately after delivery. It has growth-promoting activity, is immunologically similar to human growth hormone, and inhibits maternal insulin activity during pregnancy. By inhibiting glucose oxidation it can increase the glucose supply to a foetus developing in a malnourished mother.
