What stimulates placental growth?

Human placental growth hormone (PGH) is produced by the growth hormone (GH) variant gene on chromosome 17 (1). PGH is expressed in the syncytiotrophoblast and extravillous cytotrophoblast (EVCT) layers of the human placenta. PGH is detectable in the fetal compartment, in cord blood and amniotic fluid (2).
