Figure 3. Derivatives of Dlx5-expressing progenitors in the upper and lower jaw primordia.

Figure 3.

Sagittal section of Dlx5-creERT2; R26R-lacZ through the cephalic region of a 12.5dpc/Theiler stage 22 (ts22) mouse embryo. The pregnant dam was treated with tamoxifen at 7dpc/ts9. β-Galactosidase activity is found in CNCCs derivatives of the lower jaw (arrowheads). In contrast, in the upper jaw positive cells are only present in the overlying epithelium (arrows). mc, Meckel’s cartilage; asterisks, lower jaw muscles. Scale bar 50µm in insert, 150µm in the main figure.
