Figure 5: Effect of oxATP on serum MMP-9, MMP-2 or VEGF levels in hind limb ischemic mice. Blood of hind limb mice were collected at 14th day after ligation. (A) Activity of MMP-9 were detected by gelatin zymography (n=5/group). (B-D) Serum VEGF (n=5), MMP-2 (n=5), and MMP-9 (n=5) levels of hind limb mice were measured by ELISA. The data represent the means ± SE. Statistically significant differences are indicated by *(p<0.05) or **(p<0.01).
