WebCytotrophoblast cells proliferate in a progenitor niche (asterisk) at the proximal end of a cytotrophoblast cell column, extending from an anchoring villus (AV). The columns spread laterally at their distal ends and merge with neighbours to form the shell. WebMar 18, 2015 · The cytotrophoblast cells that form the mural and polar trophoblast are cuboidal, and covered externally with syncytial trophoblast (syncytiotrophoblast), a multinucleated mass of cytoplasm that forms initially in areas near the inner cell mass after apposition of the blastocyst to the uterine mucosa (see Fig. 8.10 ).

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 ... 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. eastlink fiber optic internet
