Fig. 5. Role of MEK and PKC pathways in cell-cell contact-mediated proliferation. Graphs of percentage of cells in S phase (A-C) and immunofluorescence images of actin (left) or ß-catenin (right) staining (D-G) in cells on agarose patterns either treated with U0126 (A,D), Ro-31-7549 (B,E), or H-7 (C,F), or untreated (G). 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 untreated controls, as calculated by Student's t-test.
