Lower jaw gene expression pattern of chondrocyte and bone markers inwls,wnt9a,wnt5bandgpc4mutants. Whole-mount RNA in situ hybridization of chondrocyte differentiation markers; sox9a (A-E) and chondrocyte matrix; col2a1 (F-J). Hypertrophic chondrocyte marker; col10a1a (K-O), Bone and tendon marker; col1a2 (P-T), osteoblastic progenitor marker; runx2a (U-Y) and joint marker; bapx1 (Z-AD). (K′-L′) 40X image focused on ceratohyal (ch; left) and both cleithrum and ceratobranchial 5 (cl, cb; right). (P′-T′) 40X images focused on dentary (de; left) and ceratohyal (right). Apparent increase in sox9a, runx2a expression pattern in wls -/- with concomitant loss of col10a1a. Black arrowhead points to the position of Meckel's cartilage. Scale=50 µm..
