VEGFA and neoplasm: We were able to confirm significant positive correlations between THb and MVD (Supplementary Fig. S7A), as might be expected for in the case of tumor blood vessels containing more blood, as well as VEGF positive area (Supplementary Fig. S7B), suggesting more angiogenic MDA-MB-231 tumors yield a higher blood content in their vascular network (MVD and VEGF were themselves significantly correlated; r = 0.60, P < 0.05).
