Etymology: Gk, syn + kytos, cell, trophe, nutrition, blastos, germ
the outer syncytial layer of the trophoblast of an early mammalian embryo. It erodes the uterine wall during implantation and gives rise to the villi of the placenta. Also called plasmidotrophoblast, syncytial trophoblast, syntrophoblast. Compare cytotrophoblast. syncytiotrophoblastic, adj.

64,81) The primary potential routes of fetal infections in general include maternal viremia with transfer from maternal blood across the syncytiotrophoblast to fetal vessels in the placenta or direct transfer at the implantation site via extravillous trophoblasts, and ascending infection from the genitourinary tract with transfer across the fetal membranes.
143) Importantly, syncytin-A knockout mice exhibit mid-fetal lethality, presumably due to a functional abnormality of one of the two syncytiotrophoblast layers, and double knockout of both syncytin-A and -B was shown to lead to a more severe phenotype and early embryonic lethality, demonstrating that they are clearly essential for syncytiotrophoblast cell formation in vivo, as expected.
