Figure 4. Amlodipine preserved normal aortic structure in the suprarenal and ascending regions.

Tissue sections from AngII-infused mice also infused with amlodipine were immunostained with alpha actin and CD68 to detect smooth muscle cells and macrophages, respectively. Positive reactivity is show by intense red color. Verhoeff’s hematoxylin staining was performed to facilitate visualization of elastin.
