Effect of CQ on tumor vascularization. a Immunohistochemistry against CD31 endothelial marker in frozen tumor sections (magnification × 200). b Quantification of CD31 signal plotted as percentage of stained area between control (sham) vs control + CQ, or irradiated vs irradiated + CQ. ***P < 0.001, ****P < 0.0001. Error bars indicate SEM for n = 3 to 14 independent experiments for each group
