what tissues does the placenta originate from
The basal plate, the peripheral region of the placenta on the maternal side that is in contact with the uterine wall, is made up of two tissues: embryonic tissue (cytotrophoblast, syncytiotrophoblast), on the one side, and of maternal tissue (decidua basalis) on the other.he fetal part of the placenta is made up of the chorionic plate with its placental villi, the cytotrophoblast layer and the intervillous spaces.
