eosin. Low magnification.
FIGURE 21.35 | Chorionic Villi: Placenta During
Early Pregnancy
The chorionic villi (6) from a placenta during early pregnancy are illustrated at a
higher magnification. The embryonic trophoblast cells give rise to the embryonic
portion of the placenta. The chorionic villi (6) arise from the chorionic plate and
become surrounded by the trophoblast epithelium that consists of an outer layer
of the darker-staining syncytiotrophoblasts (1, 10) and an inner layer of lighter-
staining cytotrophoblasts (2, 9).
