WebThe syncytiotrophoblast cell layer modulates bidirectional transport of nutrients and wastes, is responsible for most placental hormone production, and protects the inner cell mass-derived elements (the amnion and chorion membranes, the umbilical cord, and the embryo) from blood-borne maternal immune cells. From: Encyclopedia of Hormones, 2003 WebThe chorionic plate of the placenta is formed by the proliferation of cytotrophoblasts and degeneration with deposition of fibrin-type fibrinoid. Fetal allantoic vessels fuse with this layer and begin to connect with vessels formed independently within villi. In extraplacental sites, the chorion apposes the maternal capsular decidua.
WebStudy the chorionic villi in detail, and identify all of the layers that separate the maternal and fetal blood. These are: syncytiotrophoblast (outermost layer, lining maternal blood space) cytotrophoblast, which may be reduced in places. basement membrane of the trophoblast. fetal connective tissue, which may be greatly reduced in the region ...

Web4. The function of the cytotrophoblast layer of the chorionic villi is to; a) Make nutrients and oxygen accessible to developing embryo b) Differentiate into layers to form bones and muscles c) Provide secure anchorage for the placenta d) Produce human chorionic gonadotrophin hormone for maintenance of pregnancy. 5. WebSep 17, 2024 · This layer proliferates rapidly and forms numerous processes, the chorionic villi (the chorion is the layer that surrounds the embryo and extraembryonic membranes). Cyclic AMP and its analogs, and more recently hCG itself, have been shown to direct cytotrophoblast differentiation toward a syncytiotrophoblast phenotype that actively …
