Echocardiographic measurement of function.

<p>Grouped data (mean ± SEM; n≥7 per group) from A) 7 days post-injury or B) 21 days post-injury. At 7 days there was a significant increase in function only in the empty PEG hydrogel treated rats. At 21 days, only the PEG/HGF/VEGF rats demonstrated a significant increase in function compared with untreated rats (*p<0.05; ANOVA followed by Student-Newman-Keuls post-test). PEG = polyethyleneglycol, VEGF = vascular endothelial growth factor, HGF = hepatocyte growth factor, IR = ischemia reperfusion.
