Figure 2 CDX2 immunohistochemical expression. (A) Cdx2 aberrant nuclear expression in the basal layer of the squamous native esophageal epithelium close to mucosal erosion.

(B-C) Strong Cdx2 nuclear immunostain in multilayered epithelium and intestinalized columnar epithelium. (D) Strong Cdx2 expression in intestinal metaplasia and aberrant Cdx2 expression in basal squamous cells of native esophageal epithelium. (E-F) Strong Cdx2 positivity in two cases of esophageal adenocarcinoma. PI3K activity Note in E, the contrast with the Cdx2 negative native esophageal epithelium.

Non-ulcerative esophagitis was defined as sub-epithelial inflammatory infiltrate, generally coexisting with intraepithelial leukocytes; epithelial micro-erosions

were arbitrarily included in this category.

Hyperplastic lesions were defined as thickening of the squamous epithelium HA-1077 clinical trial (sometimes hyperkeratotic) with no cellular atypia. Regenerative lesions were assessed in terms of the increased length of the papillae in the lamina propria (>70% of mucosal thickness), also coexisting with hyperplasia of the proliferative compartment (>20% of the mucosal thickness) [16, 18, 25]. Metaplastic intestinalization was defined as the presence of both columnar epithelia and goblet cells [16, 18, 25]. Multilayered epithelium (MLE) is a hybrid epithelium in which both squamous and columnar epithelia coexist (“”protometaplasia”"); consistently with its phenotype, MLE expresses cytokeratins of both squamous and columnar differentiation [32].
