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 ). WebThe majority of cells in cytotrophoblast columns and shell showed nuclear reactivity with Ki67. Villous syncytiotrophoblast was uniformly unreactive with Ki67 but a proportion of the underlying cytotrophoblast was Ki67-positive throughout pregnancy. Occasional Ki67-positive trophoblast cells were identified within chorion laeve at term.
