Fig. 5 Barx1 is necessary for expression of chondrogenic markers within the pharyngeal arches. (A, C, E, G, I and K) Control embryos; (B, D, F, H, J and L) barx1 morphant embryos (see Fig. 4). Whole-mount in situ hybridization for (A, B) goosecoid (gsc), (C, D) sox9a, (E, F) runx2b, (G, H) type II collagen (col2a1), (I, J) chondromodulin (chm), and (K, L) dlx2b. Anterior is to the left; open arrowheads indicate sites of altered marker expression in the morphants; bcc, basicranial commissures; cb, ceratobranchials; ch, ceratohyal; cl, cleithrum; d, diencephalon; ep, ethmoid plate; fb, fin bud; hsc, hyosymplectic condensation; ov, otic vesicle; pq, palatoquadrate; t, telencephalon. Scale bar: 100 μm.
