WebCytotrophoblasts (CTBs) differentiate into extravillous trophoblasts (EVTs) which invade the decidua. The process of differentiation from CTBs to EVTs involves EMT [ 4 ]. DSCs contained in decidual tissue undergoing decidualization do not depend on the implantation of human embryos in each menstrual cycle. Syncytiotrophoblast (from the Greek 'syn'- "together"; 'cytio'- "of cells"; 'tropho'- "nutrition"; 'blast'- "bud") is the epithelial covering of the highly vascular embryonic placental villi, which invades the wall of the uterus to establish nutrient circulation between the embryo and the mother. It is a multinucleate, terminally differentiated syncytium, extending to 13 cm. flying ants vs winged termites pictures
