Injection of CB-MNC/HA decreases scar size and prevents wall dilatation. (A): Representative cross-section images showing the morphology of the myocardium. (B, C): Statistical analysis of scar area and wall thickness at infarct area. The values are means ± SEM (n ≥ 6). ∗, p < .05; ∗∗, p < .01; ∗∗∗, p < .001 versus MI+NS; ++, p < .01; §, p < .05. Abbreviations: CB-MNC, cord blood mononuclear cell; HA, hyaluronan; MI, myocardial infarction; NS, normal saline.
