Figure 5. Echocardiography measurements of cardiac function parameters. (A) Ejection fraction percentage at each time point. (B) Cardiac output at each time point. (C) Stroke volume at each time point. (D) Fractional shortening at each time point. Baseline n = 10-13 in all groups, week 1, 4, and 8 n = 14. **P < 0.01, ***P < 0.001, ⁺P < 0.05. EF: Ejection fraction; WJMSC: Wharton’s Jelly-derived mesenchymal stem cell; EV: extracellular vesicle; PLT: human platelet lysate; FBS: fetal bovine serum.
