Vascular endothelial growth factor expression under ischemic stress in human meningiomas.
Vascular endothelial growth factor (VEGF) is an endothelial cell-specific antigen and angiogenic factor that plays a role in angiogenesis. We analyzed the expression of four VEGF mRNA isoforms in meningiomas. Among 35 meningiomas, 11 came from patients who underwent complete (n=4) or partial (n=7206=189 in all samples. However, the VEGF121 and 165 isoforms were significantly upregulated in samples from patients who underwent partial preoperative embolization. The diffusible VEGF121 isoform may be important for vascularity and edema formation in meningiomas.
