Fig. 6. Role of the cytoskeleton 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 cytochalasin D (A-B) or latrunculin B (C-D) to disrupt the actin cytoskeleton and BDM (E-F) or ML-7 (G-H) to inhibit actomyosin dynamics. 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 untreated controls, as calculated by Student's t-test.
