Figure 3: A, Antighrelin immunohistochemical analysis of control fundus with green fluorescence and 4', 6-diamine-2-phenylindole nuclear staining (blue) reveals abundant ghrelin-positive staining in parietal cells. B, Parietal cells appear normal at hematoxylin-eosin staining. C, Green fluorescence and 4', 6-diamine-2-phenylindole nuclear staining (blue) of morrhuate sodium–treated fundus reveals markedly decreased ghrelin staining. D, Parietal cells of experimental swine are indistinguishable from parietal cells of control swine with hematoxylin-eosin staining. Bar = 100 µm.
