Placental lactogen production and functional differentiation of rat trophoblast cells in vitro

in Reproduction

Summary. Cells from the labyrinth region of the developing rat chorioallantoic placenta were able to differentiate in vitro into cells capable of producing placental lactogen. Progesterone selectively inhibited placental lactogen production by labyrinth cell cultures undergoing differentiation but had no apparent effect on lactogen production by mature trophoblast giant cells. The measurement of placental lactogen production is a useful method for monitoring the functional differentiation of rat trophoblast cells in vitro.
