Sox9 is expressed throughout the development of the submandibular gland. (A-F) Sox9 immunofluorescence (red) at the placode [E11.0 (A), E11.5 (B)], initial bud [E12.5 (C)], pseudoglandular [E13.5 (D)], canalicular [E15.5 (E)] and adult (F) stages. DNA is shown in blue (DAPI), F-actin in yellow and Mist1 in green. Dotted lines in A-D delineate the salivary gland epithelium. Insets in F show magnifications of an acinus stained for Mist1 (green) and Sox9 (red). Arrowheads point to Sox9-positive cells within the striated duct. G, ganglion; MC, Meckel's cartilage; SL, sublingual gland; SMG, submandibular gland. Scale bars: 100 μm.
