Fig. 5. Injection of sox9b mRNA partially rescues the mutant phenotype. (A,B) Wild type; (C,D) Control sox9b^b971; (E-J) sox9b mRNA-injected sox9b^b971 larvae, showing partial rescue of the craniofacial skeletal phenotype of sox9b^b971. Partial rescue occurred in 14 of 85 injected four-day-old homozygous mutant larvae. (A,C,E,G,I) Pharyngeal arches; (B,D,F,H,J) Neurocranium. Scale bar: in J, 100 µm.
