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. WebCytotrophoblasts, the inner layer of villous trophoblasts, are composed of proliferative stemlike cells, characterized by expression of p63. The isoform of p63 predominantly …
WebJan 17, 2024 · This layer is divided into two further layers: the underlying cytotrophoblast layer and the overlying syncytiotrophoblast layer. The latter is a multinucleated, continuous cell layer that covers the surface of the placenta.
