ADMSCs superiorly improved cardiac function and reduced scar size on day 28 post MI. (A, B) Intramyocardium injection of UCMSCs and ADMSCs significantly improved LVFS and LVEF after acute MI. n = 5 in sham, n = 7 in MI, n = 8 in UCMSCs and ADMSCs, respectively. (C) Representative masson’s trichrome staining of cardiac tissues. Scale bar: 1 mm. (D) quantification of scar size in each group. n = 4 in MI, n = 5 in UCMSCs and ADMSCs, respectively. Statistical comparisons were conducted using one-way ANOVA. Data are mean ± SD. *p < 0.05, ***p < 0.001, ****p < 0.0001
