 Immunohistochemical staining for glial fibrillary acidic protein (GFAP), CD34, Y‐box binding protein‐1 (YB‐1), and Ki‐67 in two glioblastoma cases. Consecutive paraffin sections from Case 1 (magnification: [A] ×40, [C] ×400) and Case 2 (magnification: [B] ×40, [D] ×400) were stained with H&E and immunohistochemically stained with anti‐GFAP, CD34, YB‐1, and Ki‐67 antibodies. Glomeruloid bodies are indicated by open‐arrow heads (A,C). Tumor vessels sprouting from pre‐existing vessels are indicated by arrows (D). PV indicates pre‐existing vessels (D).
