Figure 7: Ejection fraction was improved by stem cell transplantation. Left ventricular ejection fraction in the cell-treated groups was significantly higher than that of the saline treated control group. * A significant difference was noted between the saline group vs. human embryonic stem cell-derived cardiomyocytes (hESC-CM), the saline group vs. hESC-CM plus MSC, and between saline injected controls and animals injected with hESC+HO-1 MSC. Significance by ANOVA was p=0.0022, p < 0.05 by Tukey's test. |
