Expression of foxc1a in sox9a mutants and chondrocyte defects in Fox-C mutants
(A) Expression of foxc1a in the first two arches is unchanged in sox9a mutants at 42hpf.
(B) Confocal imaging of chondrocytes labeled by col2a1:mCherry-NTR (red) and osteoblasts labeled by sp7:GFP (green) at 72 hpf. In foxc1a; foxc1b mutants, col2a1:mCherry-NTR expression is weaker and/or reduced in the palatoquadrate (Pq), symplectic (Sy), and hyosymplectic (Hm) domains. sp7:GFP+ osteoblasts of the developing opercular bone (Op, arrows) are less affected. Numbers indicate proportion of animals showing the displayed patterns. Scale bars = 100 μm.
