FIGURE 7

Structure of the chorion laeve. Histological images of human amnio-chorionic membrane (hACM) in correspondence of the chorion laeve (hCL) and the capsular decidua (hCD). Haematoxylin-eosin staining. (A) At low magnification (20x) a general overview of this portion of the amnio-chorionic membrane, which has a smooth appearance due to the absence of chorionic villi, is appreciable. (B) At higher magnification (40x) it is possible to appreciate more cell populations present in the chorion laeve including extravillous trophoblast (hCL-EVT) and mesenchymal stromal cells (hCL-MSC).
