placental lactogen

A hormone produced by the placenta with effects similar to those of pituitary prolactin and somatotropin (growth hormone).


pertaining to or emanating from placenta.

placental barrier
the placental separation of maternal and fetal blood which varies in its structure and permeability between the species. In general the more layers of cells between the two circulations the less permeable the membrane. In none of the domestic animals are significant amounts of immune globulins or erythrocyte antigens passed through the membranes unless the epithelium is damaged. See also placenta.
placental calcification
accumulations of mineral deposit especially around the vessels and in the allantois, a normal occurrence in most species.
placental cavities
the allantoic and amniotic cavities; called also amniotic and allantoic sac.
placental edema
edema of the placenta, without necessarily any involvement of the fetus.
placental hormones
the placenta in all species produces estrogens and progesterone. In the cow it also produces lactogen, a hormone that influences structural and functional aspects of milk production. In the mare the endometrial cups produce pmsg (now called eCG) which assists in the maintenance of pregnancy. The equine, feline and primate placentae also produce relaxin which has a similar action.
placental implantation
the placenta of a viable fetus, escaped from the genital tract, can implant successfully to the peritoneum.
placental inflammation
placental lactogen
a placental hormone present in the cow's peripheral circulation at about 160 days of pregnancy; thought to have prolactin and growth-hormone capabilities.
placental mole
see mole.
placental plaques
are normal structures on the amnion in most species. They are foci of squamous epithelium.
placental removal
manual removal per vagina, detaching the placenta from each caruncle in turn.
placental transfer of immunoglobulins
see placental barrier (above) and passive immunity.

The understanding that fetal RNA in maternal plasma is predominantly placental in origin with easy and reliable detection of human placental lactogen (hPL) [3] mRNA in all pregnancy stages is in accordance with the fact that the major cell type circulating in the maternal blood is of trophoblastic, in particular extravillus, origin (5).
