Fig. 7. Role of the cytoskeletal regulator Rho in cell-cell contact-mediated proliferation. Immunofluorescence images of actin (left) or ß-catenin (right) staining and graphs of percentage of cells in S phase on agarose patterns treated with Y-27632 (A-B) to inhibit ROCK, or infected with Ad-GFP control or Ad-RhoN19 (C-D) to inhibit Rho. Broken lines (white) indicate the borders of the wells. Scale bar: 25 µm. Actin and ß-catenin images were acquired on different samples. Error bars indicate s.d. of three experiments, with (*) P<0.05 relative to controls, as calculated by Student's t-test.
