GFAP and meningioma: Meningioma cells of all subtypes of tumors were positive for human epithelial membrane antigen (EMA) (Figure 5A–C) and vimentin (Figure 5D–F) staining and desmoplakin (Figure 5G–I) staining, and negative for markers of neural cell types such as GFAP for astrocytes and β-tubulin III for neurons (data not showed).
