Vitamin D Status and Metabolism in Human Pregnancy

Completed

Conditions studied: Pregnancy

In brief

The purpose of the present study is to understand the effect of pregnancy on vitamin D metabolism and requirements as well as the modulatory role of the placenta in vitamin D metabolism during pregnancy. In addition, a human placental cell culture model will be employed to examine vitamin D metabolic flux in human trophoblast cells. The impact of maternal vitamin D status on maternal and fetal bone health during gestation will also be examined.
