Brain tumors: Cancer stem-like cells interact with tumor microenvironment

Figure 2 Hematoxylin and eosin staining and immunohistochemical staining of brain tumors. A: Hematoxylin and eosin staining displaying the pathological vessels distributed in medulloblastoma (bar, 20 µm); B: Expression of CD34 (vascular endothelial cell marker) in chordoma (bar, 20 µm); C: Expression of CD38 (T cell marker) in anaplastic diffuse astrocytoma (bar, 20 µm); D: Expression of CD68 (macrophage marker) in medulloblastoma (bar, 10 µm); E: Expression of IBA1 (microglia marker) in glioblastoma (bar, 10 µm); F: Expression of glial fibrillary acidic protein (astrocyte marker) in medulloblastoma (bar, 10 µm). GFAP: Glial fibrillary acidic protein.
