When a baby is born small, it’s often chalked up to genetics or to maternal risk factors like poor nutrition or smoking. A study of twin pregnancies, published today in Scientific Reports, finds another factor that can be measured prentally: slower transport of oxygen from mother to baby across the placenta.
Prenatal ultrasounds monitor fetal health in part by gauging blood flow from mother to fetus through the placenta. But researchers at MIT, Boston Children’s Hospital and Massachusetts General Hospital are diving deeper with magnetic resonance imaging. They’re taking advantage of MRI’s ability to measure oxygen concentrations in the placenta and fetal organs. …
The afterbirth has generally been an afterthought, but that’s about to change.
This week, 19 research centers were awarded grants from NIH’s Human Placenta Project, which is seeking to learn more about the intricate organ that sustained us in the womb, the interface between us and our mothers.
