Figure S6. Tumor vascularization. (A) Epifluorescence images of EG7 tumor sections (900 x 670 µm) after staining with anti-CD31 or isotype (red) and Dapi (blue). (B) Quantification of the vascularized area within the tumor mass of OVA-expressing (filled square) or non-OVA-expressing tumors (open square). The difference between peripheral and deep vascularization in both tumors is not significant (P > 0.05). Bar, 204 µm.
