Effect of huc-exoTIMP2 on post-MI cardiac function. (a) EF%, FS%, LVESd, and LVEDd values at 30 days after injection of exosomes. (b) Representative pictures showing the macroscopic appearance of hearts at 30 days post-MI. Arrows indicate infarcted areas. (c) Heart weight/body weight (HW/BW) ratios in different groups. (d) Representative pictures of H&E and Masson trichrome-stained heart sections in different groups. Scale bar: 50 μm.
