To determine whether angiogenesis is also involved in the antitumor effect of the systemically administered combined treatment of ADSC-E7’-eGFP with PE(ΔIII)-E7-KDEL3, the endothelial cell marker CD31 and vascular endothelial cell growth factor (VEGF) were detected 28 days after tumor inoculation. Here, VEGFA is linked to neoplasm.
