Figure 2 Representative examples of different immunohistochemical staining intensity scores for Insulin-like growth factor-binding protein 5 expression. Insulin-like growth factor-binding protein 5 (IGFBP-5) was diffusely expressed in the intestinal tissue. A: Weak staining (score = 1) (arrow) in epithelial cells in a Crohn’s disease (CD) patient without stricture formation (ileal sample); B: Moderate staining (score = 2) both in epithelial (arrow) and stromal cells (arrowhead) in a CD patient with stricture formation (ileal sample); C: Strong staining (score = 3) in epithelial cells (arrow), stromal cells (arrowhead) and crypt lumen (red arrow) in a CD patient with active disease (colonic sample). Bar = 100 μm. Images were obtained using a light-field microscope, and edited using Adobe Photoshop CS5 (Adobe Systems Incorporated).
