(20) Evaluation of the roles of prolactin and placental lactogen in pregnancy in primates has revealed mammotropic, fetal osmoregulatory, metabolic, and steroidogenic roles, which appear to protect the uterine contents during late pregnancy and prepare the fetus for the changes in nutrition at the time of delivery.
Teratological
Definition:
(a.) Of or pertaining to teratology; as, teratological changes.
Example Sentences:
(1) The importance of precocious development for planning teratological studies is emphasized.
(2) Unlike previous studies with 13-cis-retinoic acid during the pre- and early organogenic stages of development (Hummler et al., Teratology 42:263-272, 1990), no thymic hypo- or aplasia or heart anomalies were observed, which may be attributable to the slightly longer 13-cis retinoic acid treatment period, i.e., GD 10-27.
