VEGFA and peripheral arterial disease: The number of CPCs and cell migration responses to VEGF in patients with atherosclerotic PAD in the control and LIPUS groups at the 0 week of treatment (as baseline) and after 4, 12, and 24 weeks of LIPUS irradiation are shown in Figures 3-4. LIPUS irradiation for 12 weeks increased the number of CPCs from 612±280 to 1018±476/mL (p=0.01) (Figure 3) and increased to cell migration response to VEGF from 43±19 to 71±39/high-power field (p=0.01) (Figure 4).
