Fig. 5. ILK silencing enhances BAEC adhesion. Control or ILK siRNA-transfected cells were trypsinized, plated on wells coated with the indicated concentration of poly-L-lysine (PL), collagen (COL), fibronectin (FN), fibrinogen (FGN) or vitronectin (VN) and allowed to adhere for 40 minutes. Results represent the number of adherent cells (mean ± s.e.m.) from four independent experiments.
