Macrophage immunostaining of cardiac sections of HJVKO mice with advanced iron-overload cardiomyopathy. A. Representative images of macrophage (F4/80) immunostaining. B. Macrophage count derived from macrophage immunostaining of cardiac sections. Ctl=HJV control, Fe=iron diet, Fe+R=iron diet + resveratrol; values are the mean±SEM of n=6 (3 hearts; 2 sections per heart) for the control, n=8 (4 hearts; 2 sections per heart) for the iron+placebo group, n=8 (4 hearts; 2 sections per heart) for the iron+RSV group, and n=8 (4 hearts; 2 sections per heart) for the positive control (3-day MI); ND=not detected; *p<0.05 compared with the control group; #p<0.05 compared with the iron group.
