hucMSC-exosomes improved the cardiac systolic function of AMI rats 4 weeks after exosomes infusion. Echocardiographs (a). Cardiac function related parameters (LVEF, LVFS, LVID;s, LVID;d; LV Vol;d, and LV Vol;s) in hucMSC-exosomes (b) and in hucMSC-CM without exosomes treated animals (c). , , and ; ns: no significant difference between the two groups.
