WebThese hybrids may be the “seed crystal” for syncytial fusion in vitro since other pure cyto-trophoblasts may recognize these hybrids as syncytiotrophoblast. As a result normal fusion between cytotrophoblast and syncytiotrophoblast occurs in vitro similar to the situation in vivo–but is identified as fusion between two cyto-trophoblast cells. WebDuring week 2, the trophoblast divides into two layers, the cytotrophoblast and the syncytiotrophoblast. They form the embryonic component of the placenta. …

The Origin and Function of Human Syncytiotrophoblastic Giant Cells

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 … See more It is the outer layer of the trophoblasts and actively invades the uterine wall, during implantation, rupturing maternal capillaries and thus establishing an interface between maternal blood and embryonic extracellular fluid, … See more The syncytiotrophoblast lacks proliferative capacity and instead is maintained by fusion of underlying cytotrophoblast cells. This fusion is assisted by syncytin, a protein that was … See more • Cytotrophoblast • Intermediate trophoblast • Syncytium See more • Section through embryonic area of Vespertilio murinus to show the formation of the amniotic cavity. • Histopathology of a chorionic villus, … See more • Histology image: 19908loa – Histology Learning System at Boston University - "Female Reproductive System: placental villi" • Nature (Journal) Diagram See more WebThe syncytiotrophoblast, the outermost layer of the human placenta, is the main site of exchange for drugs and metabolites, nutrients, waste products, and gases … WebVacuoles appear in the syncytiotrophoblast and coalesce to form lacunae. ... - The chorion, which is composed of the trophoblast (syncytio- and cyto-) and the extraembryonic mesenchyme that lines the cytotrophoblast. - Inside the chorion, the extraembryonic coelom, which contains the embryonic disk, its amniotic cavity, and its yolk sac. ... solar panels and photovoltaic inventions
