Fig. 2: CTRP3-overexpressing MSCs improved survival, restored left ventricular cardiac function, and abated left ventricular cardiac remodeling after MI.

a The survival proportions of all groups after MI at the indicated time points (n = 19–26). b, c Echocardiographic analysis of left ventricle ejection fraction after MI at 1, 7, and 28 days for all groups (n = 5). d Gross observations and heart weight to body weight ratio (n = 5–7). e Representative masson staining for left ventricular fibrosis (n = 5). f Interstitial fibrosis 28 days after MI (n = 5). Data are means ± SEMs. *P < 0.05; **P < 0.01; ***P < 0.001. ns, not significant
