WebFeb 19, 2024 · The syncytialization process that occurs in the human placenta can be reproduced in vitro by using purified cytotrophoblasts ( Fujii et al. 2024 ), which aggregate and spontaneously fuse to form STBs. This cellular fusion process can be enhanced by EGF exposure ( Kliman et al. 1986 ). WebThe fusion of cytotrophoblast with overlying syncytiotrophoblast is a complex and highly regulated process. Several gene products that are expressed in villous trophoblast have been shown to be capable of mediating, or at least influencing, cell–cell fusion in cell lines.
