Area of Science:

  • Reproductive biology
  • Endocrinology
  • Developmental biology

Background:

  • Fetal growth is influenced by genetic and environmental factors impacting maternal capacity.
  • The placenta facilitates crucial mother-fetus exchanges and exhibits significant endocrine activity.
  • Placental size consistently correlates with birth weight across mammalian species.

Purpose of the Study:

  • To review the expression, regulation, and physiological roles of placental growth hormones (GHs) in mammals.
  • To highlight the importance of placental GHs in maternal adaptation and fetal development.

Main Methods:

  • Review of published scientific literature on placental GHs in mammalian species.
  • Analysis of data on placental structure, hormonal functions, and their relation to fetal growth.

Main Results:

  • Placental GHs are synthesized in the placenta, with some unique to this organ.
  • These hormones play a role in adapting maternal metabolism during pregnancy.
  • Placental GHs are vital for normal placental development and subsequent fetal growth.

Conclusions:

  • Placental GHs are essential for successful mammalian pregnancy.
  • Understanding placental GHs is key to comprehending fetal growth determinants.
  • Further research into placental GHs can inform strategies for optimizing pregnancy outcomes.
