Immunohistochemical staining of glioma tissues. a Strong and diffuse expression of HGF was found in high-grade glioma; b positive staining of HGF was shown focally and weakly in low-grade gliomas. c The extent of Ki-67-positive signal represented the proliferation of gliomas. Most high-grade gliomas had a high proliferation index (PI). d Intratumoral microvessels of gliomas were highlighted by staining endothelial cells for anti-CD34. Any brown-staining endothelial cell or cell cluster that was clearly separated from the adjacent microvessels was considered as a single, countable microvessel. (a-c immunohistochemical staining with original magnification, ×400; d immunohistochemical staining × 200).
