Figure Caption

Fig. 6 Fgfrl1a is essential for chondrogenesis within the ceratobranchial arches. (A/C and B/D) sox9a expression within pharyngeal domain of 60 hpf wildtype and Fgfrl1a morphant larvae, respectively. (A/B and C/D) Lateral views and equivalent sagittal sections, respectively. Asterisk in B marks absence of expression within branchial arches. (E/G and F/H) runx2b expression within pharyngeal region of 54 hpf wildtype and Fgfrl1a morphant larvae, respectively. (E/F and G/H) Lateral and dorsal views, respectively. Abbreviations: B, branchial arches; cb1–5, ceratobranchial arches 1–5; Cl, cleithrum; EP, ethmoid plate; H, hyoid arch; M, mandibular arch. Scale bars: 100 μm in A–H.
