Figures 3, 4 reveals digital images of H&E and CK18 stain in different sites (total, gastritis, IM, and adenocarcinoma). Digital analyses of IHC expression using ImageJ and ImmunoRatio software are presented in Figure 5. Figure 6 reveals different cell types (moderate differentiation and well-differentiation) gastric adenocarcinoma and IHC (VDR, Ki67 and CK18) stain. The gene discussed is KRT18; the disease is gastritis.
