Compared with the Sed-MI group, the Ex-MI group showed significant reductions of the expression of TGFβ2, COLI, COLIII, and CTGF in the infarcted area (p < 0.05) and significant reductions in the expression of TGFβ2, COLI, and COLIII in the border zone (p < 0.05). Here, CCN2 is linked to myocardial infarction.
