The morphology of IELs in the small intestine of mice (H&E staining). The arrow shows an IEL, which is small, and contains a large and round nucleus. The depth of the stain displays scattered distribution of IELs among the intestinal villus columnar epithelium, and most of the IELs are situated around the epithelial basement membrane; few IELs can be observed near the free surface epithelial cells. The scale bar represents 10 μm in the duodenum and jejunum, and the scale bar represents 10 μm in the ileum
