VEGF and FN detection by IHC. Hematoxylin-Eosin (H-E) and immunohistochemical staining of VEGF and FN in the submucosa of control ileum and in patient non-ulcerated and ulcerated ileum. The single image is representative of four IHC ileum slices. Magnifications are 4X for H-E (bar 320Â ÎĽm) and 20X for VEGF and FN (bar 100Â ÎĽm)
