Ovine placental lactogen induces somatomedin: a a possible role in fetal growth.

Ovine placental lactogen (oPL) and bovine growth hormone (bGH) increase the circulating concentration of somatomedin in hypophysectomized rats. This finding indicates that some of the somatotropic properties of oPL may be due to the induction of somatomedin and raises the possibility that oPL has a role in the control of fetal growth.
