Decrease of endogenous vascular endothelial growth factor may not affect glioma cell proliferation and invasion.

Abstract excerpt

Vascular endothelial growth factor (VEGF) is abundantly produced by glioma cells especially glioblastoma, the most malignant form of astrocytoma. VEGF, a well known angiogenic factor, acts in a paracrine fashion on endothelial cells to develop tumor vasculature. However, recent studies have found that several tumor cells express VEGF receptors, and an autocrine action of VEGF on tumor cells has been suggested. To...
