Inhibitory effect of arsenic trioxide on angiogenesis and expression of vascular endothelial growth factor in gastric cancer

Figure 1 Immunofluorescence staining for microvessel (CD31) in xenograft tumor. Microvessel or endothelial cells were identified by fluorescence staining. Original magnification × 400. A: Control group; B: 2.5 mg/kg group; C: 5 mg/kg group.

Figure 2 VEGF expression in xenograft tumor. Original magnification × 400. A: Control group; B: 2.5 mg/kg group; C: 5 mg/kg group. The fluorescence expression of VEGF in tumor cells were decreased in the arsenic-treated groups.
