Epifluorescent resolution of Elf-1 gene expression in ED 14.5 and ED20 embryos and in the adult gut. In situ hybridization analyses were performed using the control Elf-1 sense riboprobe (A, C, E, G) or the Elf-1 anti-sense riboprobe (B, D, F, H) on staged ED 14.5 day embryos (A–D), on ED20 embryos (E, F), or on adult gut (G, H). Original magnification, X20 (A–F) and ×5 (G, H). In the ED20 embryo, Elf-1 hybridized (red staining) to the thymus (T) epithelial lining of the mouth (M, arrow), epithelial lining of the lung (L), and epithelial and mucosal (Mu) layers of the stomach (St) and esophagus (Eo, arrow), but not to the muscular layers (Ml) of the stomach. In the adult gut section, Elf-1 hybridized to the epithelial and mucosal (Mu) layers of adult gut, but not to the muscular layer (Ml).
