Fig. 2From: Bystander effects of ionizing radiation: conditioned media from X-ray irradiated MCF-7 cells increases the angiogenic ability of endothelial cellsThe wound healing rate of HUVECs evaluated by in vitro scratch assay over a period of 48 h incubation of irradiated media with HUVECs (a, b). (Scale bar: 200 μm). One-way ANOVA with Tukey test was used. All values are shown as means ± SD; (3 biologically independent experiments). * P < 0.05, ** P < 0.01, *** P < 0.001, **** P < 0.0001, ***** P < 0.00001Back to article page
