Atherosclerosis plaque area assessment in aortic root of 6-mo LDLr−/− male mice.

<p>(A) Representative images of oil red-O staining of the aortic root sections in the 4 experimental groups (scale bar = 200 µm). (B) The plaque area values are presented as mean values ± SEM for n = 6 animals per group. Two-way ANOVA indicates a significant influence of post-weaning OB diet (P = 0.0002) on plaque surface.
