Figure Caption

Fig. 6 Expression of meis1.1WT in lzr mutants partially rescues jaw cartilage phenotype. (A) Alcian Green-stained wild-type embryo contains normal articulation of Meckels (M), palatoquadrate (PQ), hyosymplectic (HS) and ceratohyal (CH) cartilage elements. (B) Expression of meis1.1WT does not affect this pattern of jaw cartilages. (C) lzr mutants lack caudal cartilages, and have a prominent fusion between the second-arch derived ceratohyal (CH) and first arch-derived Meckels (M) cartilage (note arrowheads demarcating fusion). (D) lzr mutants expressing meis1.1WT have separate ceratohyal and Meckels (note the arrowheads corresponding to cartilages that are fused in panel C but not in these embryos), but do not have caudal cartilages.
