Placental Nutrient Transport and Intrauterine Growth Restriction
Intrauterine growth restriction refers to the inability of the fetus to reach its genetically determined potential size. Fetal growth restriction affects approximately 5-15% of all pregnancies in the United States and Europe. In developing countries the occurrence varies widely between 10 and 55%, impacting about 30 million newborns per year. Besides having high perinatal mortality rates these ...
متن کاملPlacental Nutrient Transport in Gestational Diabetic Pregnancies
Maternal obesity during pregnancy is rising and is associated with increased risk of developing gestational diabetes mellitus (GDM), defined as glucose intolerance first diagnosed in pregnancy (1). Fetal growth is determined by the maternal nutrient supply and placental nutrient transfer capacity. GDM-complicated pregnancies are more likely to be complicated by fetal overgrowth or excess adipos...
متن کاملExposure of pregnant mice to triclosan impairs placental development and nutrient transport
Triclosan (TCS) is associated with spontaneous abortions and fetal growth restriction. Here, we showed that when pregnant mice were treated with 8 mg/kg TCS (8-TCS mice) on gestational days (GD) 6-18 fetal body weights were lower than controls. Placental weights and volumes were reduced in 8-TCS mice. The placental proliferative cells and expression of PCNA and Cyclin D3 on GD13 were remarkably...
متن کاملReduced placental amino acid transport in response to maternal nutrient restriction in the baboon.
Intrauterine growth restriction increases the risk of perinatal complications and predisposes the infant to diabetes and cardiovascular disease in later life. Mechanisms by which maternal nutrient restriction (MNR) reduces fetal growth are poorly understood. We hypothesized that MNR decreases placental amino acid (AA) transporter activity, leading to reduced transplacental transfer of AAs. Preg...
متن کاملMaternal fetal/placental interactions and abnormal pregnancy outcomes.
Cytotrophoblast cells from the placenta invade the maternal spiral arteries during normal pregnancy. This results in a striking increase in luminal diameter and causes the vessels to lose their smooth muscle enabling the expansion of vascular capacity necessary to support fetal growth. Preeclampsia, growth restriction, recurrent abortion, and preterm birth in many cases are caused by abnormal i...
