    Pediatric patients with EE have increased subepithelial fibrosis and TGF-β1. A-D, Trichrome stain of normal, GERD, EE esophageal biopsies and fibrosis score. E, Representative image of EE biopsy stained for TGF-β1 (red; inset shows green nucleus). F, Quantitated TGF-β1–positive cells in normal patients, patients with GERD, and patients with EE. G-I, Eosinophils express MBP (red), TGF-β1 (green), or both (yellow). ∗∗P < .005.

A-F, Representative image of phospho-SMAD2/3 staining in epithelial (EPI) and lamina propria cells in patients with GERD (arrows show phopho-SMAD2/3–negative nuclei) and patients with EE. G-I, A subset of actively proliferating epithelial cells coexpress (yellow) MIB-1 (green) and phosopho-SMAD2/3 (red). J, Quantitation of phospho-SMAD2/3–positive cells in normal, GERD, and EE.
