title: The presence of gonadotropin and prostaglandin E receptors in the cell membranes of bovine corpora lutea throughout pregnancy.
abstract: These studies revealed that the cell membranes prepared from bovine corpora lutea contain receptors for both human chorionic gonadotropin and prostaglandin E throughout pregnancy. The presence of these receptors correlated well with the earlier findings that the corpus luteum remains functional and responds to gonadotropic stimulation throughout the bovine pregnancy. This contrasts with our earlier findings that human corpora lutea of pregnancy of more than 6 weeks contain very few or no available receptors for human chorionic gonadotropin or prostaglandin E.
