Figure 2From: The expression of cytoglobin as a prognostic factor in gliomas: a retrospective analysis of 88 patients Immunohistochemical staining of IL-6, TNFα and VEGF in low and high grade of glioma tissues. Low-grade gliomas showed low expression of IL-6 (a), TNFα (b) and VEGF (c) positive tumor cells in serial section. High expression of IL-6 (A), TNFα (B) and VEGF (C) was shown in high-grade gliomas.
