Circulating Proangiogenic Cells and Proteins in Patients with Glioma and Acute Myocardial Infarction: Differences in Neovascularization between Neoplasia and Tissue Regeneration

Figure 5

Correlation between plasma factors and EPC subtypes. Correlation is significant at the 0.01 level (2-tailed). Correlation is significant at the 0.05 level (2-tailed). We used Spearman’s rho to calculate correlation coefficients between plasma factor and EPC subtype levels. Figure 5 shows Spearman’s rho for significant correlations between EPC levels and plasma factor levels in MI and GBM patients. Blue color indicates a negative correlation between plasma factor and EPC frequency; red indicates a positive correlation. For a complete overview (including CD13 and CD133^- HPC subtypes and correlations between EPC frequencies and plasma factors in all samples grouped together), see Additional File 2.
