Canstatin prevents cardiomyocyte hypertrophy in non-infarcted area after MI. Recombinant mouse canstatin (20 μg/kg) or vehicle was intraperitoneally administered for 28 days after LAD ligation in rats. The hearts were isolated and then thin paraffin Sects. (4 μm) were made. (A) Representative hematoxylin and eosin stained pictures of the non-infarcted areas from SHAM + vehicle, SHAM + canstatin, MI + vehicle and MI + canstatin groups were shown. Scale bar: 100 μm. (B) Cross-sectional diameter of cardiomyocytes was measured (50 cells/heart) and shown as mean ± S.E.M. (SHAM + vehicle and SHAM + canstatin: n = 6; MI + vehicle and MI + canstatin: n = 8). **P < 0.01 vs. SHAM + vehicle, ## P < 0.01 vs. MI + vehicle (two-way ANOVA followed by Tukey’s post hoc test).
