Flow cytometric analyses of circulatory levels of inflammatory biomarkers and endothelial progenitor cells by day 3 after AMI induction. A. Circulatory level of Ly6G+ cells, * vs. other groups with different symbols (†, ‡, §), P<0.0001. B. Circulatory level of CD11b/c+ cells, * vs. other groups with different symbols (†, ‡, §), P<0.0001. C. Circulatory level of myeloperoxidase (MPO)+ cells, * vs. other groups with different symbols (†, ‡, §), P<0.0001. D. Circulatory number of C-kit/CD31+ cells, * vs. other groups with different symbols (†, ‡, §), P<0.0001. E. Circulatory number of Sca-1/CD31+ cells, * vs. other groups with different symbols (†, ‡, §), P<0.0001. F. Circulatory number of KDR/CD34+ cells, * vs. other groups with different symbols (†, ‡, §), P<0.0001. G. Circulatory number of VE cadherin/CD34+ cells, * vs. other groups with different symbols (†, ‡, §), P<0.0001. (n=6 for each group). SC = sham-operated control; AMI = acute myocardial infarction; EPO = erythropoietin; UNC = UNC0638, a G9a inhibitor.
