Histopathological confirmation of similar intramucosal distribution of fluorescein in both intravenous administration and local mucosal application for probe-based confocal laser endomicroscopy of the normal stomach

Figure 4 Histology 5 min after local mucosal application of fluorescein. A: HE staining of biopsied tissue (original magnification × 200); B: Fluorescence observed in the serial section of Figure 4A. Green fluorescence is observed in more fundic glandular cells compared with that at one minute (non-HE staining; original magnification × 200); C: The region in the red square is magnified. Green fluorescence is noted around the nuclei (light blue) of fundic glandular cells.
