Fig. 4

pk1b and pk1a mutants do not show alterations in pharyngeal cartilage fates. (A-C) In situ hybridizations for the pharyngeal neural crestmarker dlx2 in WT (A), pk1b ^{fh122/ fh122} (B) and pk1a^ch105/ch105 (C) 24 hpf embryos in lateral view show no significant differences between conditions. Solid arrowheads indicate streams of NCCs. (D-F) Alcian Green labeling of cartilage elements of the pharyngeal apparatus in WT (D), pk1b ^{fh122/ fh122} (E) and pk1a^ch105/ch105 (F) 6 dpf larvae, show no significant changes in size and organization of elements between conditions. m=Meckel’s cartilage; pq=palatoquadrate; ch=ceratohyal; cb=ceratobranchial; cb(i) indicates first branchial arch, cb(iv) indicates fourth branchial arch, with solid arrows indicating the corresponding ceratobranchial cartilage elements.
