Figure 6 Endothelial alkaline phosphatase stain (x400 magnification). (A) In the regions adjacent to the scar, capillary density was significantly higher in a rat from HGF-US/MB than those from other groups (top). No significant differences were noted among the groups in the capillary density in the remote non-infarcted regions (bottom). Bar graphs compare the vessel count per high-power field (HPF) among the groups for the regions adjacent to the scar (B) and for the remote non-infarcted regions (C). *p < 0.05 versus pVax1-US/MB, HGF-US, and HGF-alone. Abbreviations as in Figure 3.
