Plate 1
1 Drawing of cytotrophoblast cell showing two granules in the Golgi region with associated mitochondria. (black). A large vacuole is present at the right of the sgvncytial nucleus. Case 6. About x 4300.
2 Drawing of the syncytium showing minute granules in the subnuclear zone in association with clear curved channels, the negative image of the Golgi apparatus. The granules increase in Size towards the surface of the syneytium and show varied degrees of affinity for aniline blue. The majority are homogeneous; one large granule at upper right shows definite structure. Superficial vacuoles at upper left. Mitochondria. have accumulated in the supranuclear zone and about the negative image of the Golgi apparatus. Case 12. About x 3200.
3 Accumulation of mitochondria in the superficia.l- zone of the syllcytium in the absence of vacuoles and granules. Mitochondria (black) are shown in the cytotrophoblast cell, especially in the Golgi region at the left of the nucleus. The syncytial nuclei are more chromatic than those of the cytotrophoblast. Case 12. x 1160.
4 Secretory granules in the superficial zone apparently in various stages of liquefaction, with some eecuxnuluted mitochondria. A cytotrophoblast cell (arrow) appears above the capillary probably in process of transformation to syncytium. The cytoplasm is dark, and the mitochondria at left of nucleus, large and intensely stained. Contrast cytoplasm to that of cytotrophoblast cells in figures 3 and 5. Case 12. x1160.
5 Reguklar brush border and even distribution of mitochondria throughout syncytium. Some lipid droplets (black) in the syncytium. 01min of mitochondria above nucleus of middle cytotrophoblast cell. Case 12. x 1160.
6 Brush border after Bouin fixation. Case 13. x 1160.
