Mast cells in human cerebral and meningeal tissues. (A) Antitryptase-stained section of the human cerebral cortex showing predominantly spindle-shaped MCs (arrows) in the characteristic perivascular position. Modified with permission from Ann Med 2009; 41:438–450. (B) A round/oval perivascular mast cell in human cerebral ischemia typically expressing CD117 (arrows). Thin arrows point to the nuclei of endothelial cells. (C) Anti-tryptase staining showing MCs (arrows) in human meningeoma.
