Oscillatory Shear Stress Induces Oxidative Stress via TLR4 Activation in Endothelial Cells

Figure 5

Colocalization of eNOS and caveolin-1 in the aortic arch. (a) Caveolin-1 and (b) eNOS were used to stain the aortic arch. (c) Nucleus was identified with DAPI. (d) A merged figure in which the outer and inner curves (the outer curve is where shear stress is high, and the inner curve is where shear stress is low and oscillatory) were enlarged.
