Figure 1

Percentages of CD34+ and VEGFR2+ cells in patients with malignant and benign breast diseases compared with that of healthy controls as determined by flow cytometery.
(A) Forward and side scatter evaluations were used to generate the analysis gate (left panel). The upper right panel shows negative controls stained with PE- and FITC-labelled IgG isotype controls. The lower right panel contains cells stained with anti-CD34-FITC and anti-VEGFR2-PE. The percentage of the population that expressed the indicated antigens CD34+ and VEGFR2+ is shown in each quadrant. (B) The incidence of CD34+ VEGFR2+ cells in whole blood from patients with malignant breast diseases (n = 27), those with benign breast diseases (n = 19), and healthy controls (n = 10). Bars, SE; *p < 0.05.
