Fig. 5 fscn1a is required for development of NC-derived craniofacial cartilage.
(A) Lateral views of wild type (wt) and fscn1a MZ 5 dpf embryos. Arrow indicates reduced jaw in fscn1a MZ embryos. (B) Lateral (left) and ventral (right) views of Alcian blue-stained wt and fscn1a MZ 5 dpf embryos. Numbers correspond to pharyngeal arches. Arrow indicates missing palatoquadrate in fscn1a MZ embryos. (C) Ventral view of dissected Alcian blue-stained pharyngeal skeletons from wt and fscn1a MZ 5 dpf embryos. ch = ceratohyal, cb = ceratobranchial, hm = hyomandibular, hs = hyosymplectic, mk = Meckel’s cartilage, pq = palatoquadrate.
