Expression patterns of Pax9 in different taste papillae of the embryonic mouse tongue

A. Drawing showing the localization of the circumvallate papilla (CVP), foliate papillae (FOP), and fungiform papillae (FUP) in the mouse tongue.

B. Whole mount X-Gal staining of a Pax9+/LacZ mouse tongue at embryonic day 13.5 (E13.5). Note that expression is also seen in the mesenchyme adjacent to the developing FOP (arrowheads) and that the color reaction was stopped before epithelial staining began to obscure the mesenchymal expression domain.

B Scale bar 200 µm.
