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 2 Probe-based confocal laser endomicroscopy images of normal fundic glands mucosa of the stomach. A: Image employing intravenous fluorescein administration. Regular round or oval foveolar lumina with homogeneous epithelial cells are visualized, showing dark images; B: Image employing the local mucosal application of fluorescein. Regular round or oval foveolar lumina with homogeneous epithelial cells are visualized, showing dark images of the foveolar epithelial cells and bright images of the foveolar lumina.
