WebAug 2, 2016 · 2 layers in Trophoblast: 1. Inner mononulcear Cytotrophoblast (Cellular) Mitotic figures are found in the cytotrophoblast – hence generate primary chorionic villi into the syncytiotrophoblast. 2. Outer multinucleated Syncytiotrophoblast (Syncytium – cells have fused) Mitotic figures are absent in syncytiotrophoblast – hence, doesn’t divide. Websyncytiotrophoblast the multinucleated trophoblast that forms the outer layer of the chorionic villi responsible for nutrient exchange and hormone production. I. Introduction The precursor cells of the human placenta—the trophoblasts—first appear four days after fertilization as the outer layer of cells of the blastocyst.

WebThe bilaminar disc forms the dividing layer between the yolk sac and amniotic cavity. Trophoblast. The trophoblast is the layer of cells that surrounds the blastocyst. During week 2, the trophoblast divides into two layers, the cytotrophoblast and the syncytiotrophoblast. They form the embryonic component of the placenta. Cytotrophoblast WebCytotrophoblasts secrete enzymes enabling the embryo to get fully covered by the endometrial epithelium. If the cytotrophoblast function is inadequate, implantation of the blastocyst will most likely fail. The syncytiotrophoblast layer extends over the placental surfaces of all villous trees, completely lining the intervillous space.
