High expression of IL-34 in ductal epithelial cells and endothelial cells of blood vessels correlates with high infiltration of immune cells. Representative data of IL-34 staining by IHC showing the localized expression of IL-34 in ductal epithelial cells and endothelial cells of blood vessels. Hematoxylin staining demonstrates lymphocyte accumulation around IL-34-expressing epithelial (red arrows) or endothelial (green arrows) cells. Scale bars, 20 μM
