Fig. 7From: The tongue of the red-eared slider (Trachemys scripta elegans): morphological characterization through gross, light, scanning electron, and immunofluorescence microscopic examinationImmunofluorescence staining of Synaptophysin (Green) and DAPI (Blue) in the red-eared slider’s tongue. Panel A-F illustrates the presence of Synaptophysin within nerve bundles (NB) located in the lamina propria of fungiform papillae, as well as its expression within the taste bud cells (TB) situated on the epithelial surface of the fungiform papilla in the tongue of the red-eared slider. Panels D-F provide a closer view, showing a higher magnification of Synaptophysin expression within the taste bud cells on the epithelial surface of the fungiform papilla in the red-eared slider’s tongue. Scale bars: A-C = 100 μm, D-F = 50 μmBack to article page
