👉 Crown fluid, also known as corioid fluid or crown cells fluid, is a clear, watery secretion produced by the corioide cells, specialized mesenchymal cells found in the basement membrane of the placenta. These cells play a crucial role in the placental structure and function, particularly in nutrient and gas exchange between the maternal and fetal circulations. The fluid is rich in proteins, lipids, and various growth factors, facilitating the transport of essential nutrients and waste products. Additionally, it helps maintain the structural integrity of the placental barrier, ensuring a stable environment for fetal development.
