WebTrophoblasts are cells that form the outer layer of a blastocyst, which provides nutrients to the embryo, and then develop into a large part of the placenta. Trophoblast invasion is a critical process in the establishment of a successful pregnancy. "Cytotrophoblast" is the name given to both the inner layer of the trophoblast (also called layer of Langhans) or the cells that live there. It is interior to the syncytiotrophoblast and external to the wall of the blastocyst in a developing embryo. The cytotrophoblast is considered to be the trophoblastic stem … See more The formation of all syncytiotrophoblast is from the fusion of two or more cytotrophoblasts via this fusion pathway.

WebAs nouns the difference between cytotrophoblast and trophoblast is that cytotrophoblast is (cytology) the inner layer of the trophoblast while trophoblast is (cytology) the membrane of cells that forms the wall of a blastocyst during early pregnancy, providing nutrients to the embryo and later developing into part of the placenta. WebSyncytiotrophoblast (STB) is responsible for nutrient and gas exchange in the human placenta. STB also forms when human embryonic stem cells (ESCs) differentiate to trophoblast. Here we compare ESC-derived STB with cytotrophoblasts isolated from term placentas before and after such cells had fused to form STB. the permutation symbol
