Vß3 WT cells were adhered to vitronectin-coated coverslips in the presence of Rho kinase (ROCK) inhibitor, Y27632 (10 µM) (A-C) or Y27632 and PMA (10 ng/ml) (D-F) for 10 (A,D), 30 (B,E) or 70 (C,F) minutes. Cells were stained for ß3 Y747 PSSA and FITC-conjugated secondary antibody as described in Materials and Methods. Bar, 5 µm.
