Fig. 5. Blocking free FN sites. BAECs were plated on FN-coated slides for 2 h in the absence of serum and then incubated with anti-FN Fab fragments for 15 min. Cells were either sheared (5 min, 12 dynes/cm²) or kept as static control and Rho assayed. Values are means ± SEM (n = 3, each in duplicate) relative to static samples.
