Plate 5. Drawing of group of Cytotrophoblastic Cells

11 This drawing of an group of cytotrophoblastic cells demonstrate stages in the transition of this tissue to syncytium. At ‘a’ the cytoplasin stains similarly to that of syncytium and there is a loss of cell membrane with fusion with the cytoplasm of the adjacent cell. The cell ‘c’ has acquired 21 faint brush border. While the cell ‘b’ is still a distinct cytotrophoblastic cell, it is larger and has a well-developed brush border. The syncytial mass ‘e’ represents the end process of the forination of the multinucleated syncytium with a well-formed brush border.

The cells ‘d’ demonstrate phagocytic activity similar to that of other trophoblastic elements noted in figures 26, 27, 28, 29 and 30.
