Effects of HO-1-MSCs transplantation on ventricular function. (A) Hemodynamic assessment of cardiac function at 4 weeks after transplantation. LVSP: left ventricle systolic pressure; LVEDP: left ventricle end-diastolic pressure; + dP/dtmax and -dP/dtmax: rate of rise and fall of ventricular pressure, respectively. means ± SD of data from 6 separate experiments, *P < 0.05 compared with the hearts treated with PBS, #P < 0.05 compared with the hearts treated with Null-MSCs. Lane a, hearts treated with PBS; Lane b, hearts treated with Null-MSCs; Lane c, hearts treated with HO-1-MSCs.
