Figure 4. Anterior neural crest cells of the dact1/2−/− mutant migrate to the midline and populate the dysmorphic ethmoid plate.

Lineage tracing of wildtype and dact1/2−/− double mutant zebrafish embryos using Tg(sox10:kaede) line. sox10:kaede fluorescence is shown in green and photo-converted kaede is shown in magenta and highlighted with an arrow. Asterisks indicate that the cell population is absent. (A, B) 19 hpf embryo sagittal views showing photoconversion of anterior-most neural crest population. At 36 hpf frontal images show the migration of photoconverted neural crest cells to the frontal prominence in wildtype and dact1/2−/− double mutants. At 55 hpf, frontal images show photoconverted neural crest cells populating the region of the developing anterior neurocranium (ANC) in wildtype and dact1/2−/− mutants. At 4.5 dpf ventral images show photoconverted neural crest cells populating the medial ethmoid plate in wildtype. Similarly, neural crest cells in dact1/2−/− mutants populate the rod-shaped ethmoid plate. Scale bar: 100 μm. Representative images of three individual experiments.
