Collagen content 28 days after myocardial infarction. (A) Representative pictures of left ventricles from each group after Masson's Trichrome staining (magnification, ×200). (B) Collagen content as percentages at 28 days. Collagen content is calculated from the ratio of the collagen area to the area of the entire high-power field. The data are expressed as the mean ± standard deviation. *P<0.05 vs. sham, #P<0.05 vs. NS. n=6 in each group. NS, saline group.
