Fig. 10From: The tongue of the red-eared slider (Trachemys scripta elegans): morphological characterization through gross, light, scanning electron, and immunofluorescence microscopic examinationImmunofluorescence staining of CD20 (Red) and DAPI (Blue) in the lingual tonsil of the red-eared slider. Panels A-C provide a lower magnification view, while Panels D-F present a higher magnification view, revealing the distribution of lymphoid tissue in the tongue of the red-eared slider. Lymphocytes (L) are found in various locations, including diffuse lymphoid tissue (DLT), dorsal organized lymphoid tissue (OLT) in lingual epithelium (EP), crypt (C), and sparsely within the lamina propria of dense irregular connective tissue (LP).
