Expression pattern of c/ebp1 in zebrafish embryos.
RNA in situ hybridization was performed with a digoxigenin-labeledc/ebp1 RNA antisense probe. (A) Lateral view of 20-somite embryo with arrow indicating c/ebp1-expressing cells overlying yolk sac. (B) Lateral view of 24-hpf embryo withc/ebp1-expressing cells on the yolk sac (arrow) and in the axial vein (arrowhead). (C) Lateral view of 2-dpf embryo withc/ebp1-expressing cells in the axial vein and surrounding mesenchyme (arrowhead) and in mesenchyme of the head (arrow). (D) Yolk sac at 20 × magnification in a 24-hpf embryo using a Microphot AX compound microscope. Boxed area is shown in higher magnification in panel E. (E) Yolk sac at 40 × magnification in a 24-hpf embryo using a Microphot AX compound microscope.
