Fig. 10 Sox32 function is required for the migration but not differentiation of endocardial precursors. (A–D) Fn1 expression in the endocardial precursors is not affected in the endoderm-deficient sox32 knockdown embryos at the 12-somite stage (A,B) while they fail to migrate towards the midline at the 16-somite stage (C,D). (E,F) Endocardial kdrl expression is absent from the midline in sox32 morphants at the 18-somite stage. (G–L) Myocardial cmlc2 (G,H,K,L) and endocardial NFATc1 expression (I,J) is split bilaterally in sox32 morphants at the 20-somite (G,H) and 26 hpf stages (I-L). Ventral view of flat-mounted embryos, anterior is to the top in all panels.
