Understanding Human Placental Biology

NICHD’s Human Placenta Project (HPP) supports research to better understand placental biology because the structure and function of the placenta can affect pregnancy and future health outcomes. Learn about research groups using ultrasound technology, cell-free DNA/RNA screening, placentomics technology, and more to better understand the basic biology of the placenta.
