Fig. S2.
Expression of emx2, nkx3-2-b, nkx3-3, hand1, hand2-a msx1-b, and msx2. Gene and stage are indicated in figure. Anterior to left in all lateral views, anterior to top in E, N, dorsal to top in II. For those genes with a section shown, the plane of section is shown as a red line on the corresponding whole-mount panel. (J and N) nkx3-3 is expressed in CNCCs where the primary jaw joint will eventually form (arrow). |

Fig. 3. Expression domains in the forming suprarostral plate, ethmoid plate, and trabecular cartilages at st. 37/38. Anterior to left in all panels. (A) Whole-mount lateral view of satb2 at st. 37/38; red line depicts the approximate plane of section used to assess gene expression in all subsequent panels. (B) satb2 is expressed dorsal to the PAs in the suprarostral plate at st. 37/38. (C) alx4 marks all aspects of the future neurocramium ventral to the eyes and brain. (D) prrx2 is found only in a lateral subset of the suprarostal plate, ethmoid plate, and trabeculae. (E) gsc-b is detected in the trabeculae and a small portion of the lateral ethmoid plate. (F) msx1-b is expressed strongly in the future suprarotal plate. (G) A summary scheme of the expressions shown in (B)–(F). |
