Histological and immunohistochemical analysis for HER2 expression in human GC. ac Gastric tumor and non-tumor sections were stained with hematoxylin and eosin (HE). d–f Histopathological conformation of non-tumor and cancerous tumor tissues of gastric specimen were stained with methylene blue (MB). gl Representative IHC staining images of GC sections for HER2 and mki-67 expressions. The nuclei of GC cells were clearly stained. HER2 (gi) and mki-67 (j–l) were obviously expressed in stage 1–2 and stage 3–4 gastric tumor tissues, but weakly expressed in adjacent non-cancerous tissues. Magnification: ×400, scale bar: 50 μm
