Dhx15−/− zebrafish displayed defective definitive hematopoiesis in CHT. A‐B’, WISH analysis of cmyb expression in dhx15+/+ and dhx15−/− at 3 dpf (A, A’) and 4 dpf (B, B’). C‐F’, WISH analysis of mpx (C, C’), l‐plastin (D, D’), hbae1 (E, E’), rag1 (F, F’) expression in dhx15+/+ and dhx15−/− zebrafish. G‐I’, WISH analysis of cmyb expression in dhx15+/+ and dhx15−/− zebrafish at 36 hpf (G, G’), 48 hpf (H, H’), 60 hpf (I, I’). Black arrows indicate CHT; red arrows indicate ventral wall of dorsal aorta; red arrowheads indicate thymus. CHT, caudal hematopoietic tissue; dpf: days post fertilization; hpf, hours post fertilization; WISH, whole‐mount in situ hybridization
