Figure 9
Cellular localization of activated caspase 8 and non-junctional occludin. Cells were grown and stained as in Figure 7A except that the apical plasma membrane marker MUC1 (red, third panel, white 4th panel) was stained in place of caspase 3. Two sets of white lines in the first panel show the plane of two slightly different digital XZ-sections projected above and below the central XY image in this composite image.
