Cytotrophoblast forms

WebThe large multinucleated syncytiotrophoblast is formed by the fusion of underlying cytotrophoblasts, which facilitate its expansion as the placenta grows. The syncytiotrophoblast layer also undergoes constant turnover, with older regions being shed from the placental surface by apoptotic mechanisms. WebApoptosis was hypothesized to play a central role in the turnover of cytotrophoblast and syncytial surface chorionic villi renewal via controlled cell fragmentation. 33 This was further strengthened by increased concentrations of other circulating markers of syncytial debris including cytokeratin or cytoskeleton protein 34 and fetal DNA. 35 ...
