WebApr 15, 2024 · The CTB originates two main villus structures: the floating villus, where CTBs fuse to form the multinuclear syncyiotrophoblast (STB) and the anchoring villus ( 17 – 20) ( Figure 1 ). The STB acts as an exchange barrier with the maternal blood to assure nutrients as well as waste and gases exchange with the fetal blood ( 21 ).

Trophoblasts are specialized cells of the placenta that play an important role in embryo implantation and interaction with the decidualized maternal uterus. The core of placental villi contain mesenchymal cells and placental blood vessels that are directly connected to the fetus’ circulation via the umbilical cord. This core is surrounded by two layers of trophoblasts, the cytotrophoblast and the syncytiotrophoblast. The cytotrophoblast is a layer of mono-nucleated cells that resides …
