Plate 11

22 This is a photomicrograph of a portion of one wall of an endometrial gland in the penetration zone. The gland lumen is partly filled with blood that is deeply stained. The epithelial cells all show evidences of degeneration, while those near the middle of tho figure have been almost completely destroyed. The cytoplasm which remains is clumped about the nucleus. Approximating this cell is fetal trophololast. Adjacent to the gland wall there is a large mass of trophohlast, some of which has penetrated that structure. X 395.

23 Surrounding this portion of an endometrial gland in the penetration zone there is a syncytial cell mass. This mass has af brush border. The endometrial gland cells are markedly degenerated and in places entirely wanting. The gland lumen contains blood. X 395.

24 This endometrial gland projects partly into the irnplantation cavity. That portion in the cavity has been almost completely destroyed and surroundcd by syncytium. In. the lumen of the gland there is an organizing blood clot as well as some fresh hemorrhage. The brush border of the syncytium appears dark. X 202.

25 The surface epithelium of the decidua is shown with the overlying coagulum (soc figs. 2 and 5). The coagulum consists of maternal blood cells, some degenerated maternal stromal cells, and fetal trophoblast. Two fetal cells are shown in the process of penetrating the surface epithelium. The epithelium about this point is necrotic. X 393.
