Fig. 7. Simultaneous relocation of caveolin-1 and G_q/11 in response to shear stress. Endothelial cells were exposed to a shear stress of 20 dynes/cm² for 24 hours. Endothelial cells were exposed to laminar shear stress (arrow indicates direction of flow) as described in the legend to Fig. 2. Cells were then fixed and processed to localize the indicated protein. Bar, 30 µm.
