Histomorphological Characteristics and Pathological Types of Hyperproliferation of Gastric Surface Epithelial Cells

Figure 2

The histomorphologic characteristics of drug-induced hyperplasia of gastric epithelial cells. (a) H&E results showing no or very little inflammatory cell infiltration in the stroma, with the height of hyperplastic gastric epithelial cells between 1 and 1.5 mm and cells arranged in a monolayer. (b) Immunohistochemical staining results showing positive expression of MUC5AC. Characteristic images of each group at 200x objective magnification were shown.
