Figure 3.

Hematoxylin-eosin stained sections showing villi of mucosal explants cultured for 1 h in the absence (A) or presence of 2 mM of LC (B), DG (C) or C₁₂E₉ (D), as described in Methods. All 3 PEs caused denudation at foci near the villus tips (arrows), whereas the epithelium along the sides of the villi generally remained intact. Enterocytes (E) and lamina propria (LP) are indicated. The images shown of each situation are representative of at least 5 images. Bars: 50 µm.
