Within the groups with malignant and benign breast disease patients, the number of EC-CFUs and the percentage of CD34+ VEGFR2+ double-positive cells failed to be correlated (Spearman r = −0.1926; p = 0.3358 and r = 0.3238; p = 0.1762, respectively), as shown in Fig. 3A. This evidence concerns the gene CD34 and breast fibrocystic disease.
