Figure 6. Effects of combination treatment on tumor size. At the end of treatment, mice were euthanized and tumors extracted and pictures taken using a Nikon camera. After three immunizations BALB/c mice were challenged with TUBO cells and treated with VEGF-P3 and VEGF-P4. Representative photos from different treatment groups at day 39 after the inoculation of cancer cells are reported. (A) untreated; (B) irrelevant; (C) MVF-HER-2; (D) MVF-HER-2+IRRELEVANT; (E) MVF-HER2+VEGF-P3(CYC); (F) MVF-HER2+RI-VEGF-P4(CYC).
