WebCytotrophoblasts function as undif-ferentiated progenitors for both the overlaying syncytiotrophoblasts and the extravillous invasive trophoblasts that serve to anchor the placenta into the maternal uterine wall (11). Throughout pregnancy, the cytotrophoblasts are mitotically active until fusion, which ultimately forms a syn- WebSyncytiotrophoblasts. As shown in Table 1, 790 genes are elevated in Syncytiotrophoblasts compared to other cell types. Syncytiotrophoblasts form when undifferentiated and highly proliferative cytotrophoblasts fuse.
