Italic letters within images refers to: for the gallbladder s: serosa layer, ms: muscularis layer, m: mucosa layer, lp: lamina propria, ce: columnar epithelial cells, and f: fibroblasts; duodenum and colon me: muscularis externica layers, sm: submucosa, mu: mucosa, cl: crypts of Lieberkuhn (tubular glands), mm: muscularis mucosa, and v/a: vein/artery. Scale bars in large sections and in isotype control sections (C,F,G) correspond to 500 µm and in small sections to 50 µm.
