Understanding the molecular control of placenta formation, the organ which enables fetal growth, is critical in diagnosing and treating related pregnancy complications. A group of scientists at the Chinese Academy of Sciences, Beijing, China, and the University of Calgary, Canada has revealed a molecular feedback loop that governs the earliest steps of placenta formation in mice, which is known to mimic placenta formation in humans. Their findings are published April 16 in the open access journal PLOS Biology.
