Fig. 3

Epithelial and stromal cells after 7 days in culture. Epithelial cells make up the top half of the panel (arrow at right); they are still loosely associated but the connexions between them (I, D, as shown in Fig. 1a) have become scarce. Lipid inclusions (L) and lysosomal remains (LR) have further increased in size. The basal membrane (Bm, separating the two cell types through the middle of the panel) is only partially visible. The bottom half of the panes (arrow at right) shows degerated stromal cells, with condensed chromatin (kC), phagosomes (Ph), and lysosomal remains. Magnification ×7,650
