Protein expression of CXCR4 in ischemic quadriceps at day 14 after critical limb ischemia (CLI) induction. (a) At sham control (SC) treatment condition, CXCR4 did not differ among four groups, . (b) At CLI subgroup, groups with different symbols (, , , and ), . (c) At SC + tPA subgroup, CXCR4 did not differ among four groups, . (d) At CLI + tPA subgroup, groups with different symbols (, , , and ), . All statistical analyses were performed by one-way ANOVA followed by Bonferroni multiple comparison post hoc test. tPA = tissue plasminogen activator. for each group.
