INSULIN-LIKE GROWTH FACTORS AND PLACENTAL FUNCTION
Published online by Cambridge University Press: 01 August 2007
Extract
Placentas from different species differ not only in their cellular structure and normal trajectory of growth but also in the architecture of their placental vasculature and the transport and exchange mechanisms that determine nutritional transfer from mother to fetus and waste disposal from fetus to mother.1 Many maternal and fetal hormonal and nutritional factors, as well as placental paracrine and autocrine systems affect placental growth and development throughout gestation.2 Nutrients delivered from the maternal circulation are as important for placental growth as they are for fetal growth. In addition to passing across the placenta to provide the building blocks for fetal growth, amino acids, carbohydrate and lipids are incorporated into the placenta.
