2. Figure 1
Peritoneum biopsy showing the distribution of the α2β1 integrin in mesothelium. M = mesothelial cells. Arrowheads illustrate expression on the basal plasma membrane. Arrows illustrate expression at the cell surface. (CLSM, original magnification, ×750; bar = 10 μm).

3. Figure 2
Peritoneum biopsy showing the distribution of the α3 integrin subunit in mesothelium. Expression of the α3 integrin is seen at the base and surface of the cell. Diffuse labeling is seen throughout the cytoplasm. (CLSM, original magnification, ×450; bar = 10 μm).

4. Figure 3
Distribution of the α2β1 integrin subunit in a mesothelial cell grown on Aclar film. There is decreased expression at the base of the cell (arrowheads) and stronger expression at the cell surface (arrows). (TPLSM, original magnification, ×1,050; bar = 5 μm).
