Syncytiotrophoblast

Definition

The syncytiotrophoblast is a layer of multinucleated cell tissue that forms part of the placenta, arising from the outer layer of the blastocyst and playing a crucial role in nutrient exchange between the embryo and the mother. It embeds the developing embryo into the uterine wall and facilitates the formation of embryonic part of the placenta.
