  Fig. 3. Id4 mRNA expression pattern in the early embryo. (A, C, E, G) Dorso-anterior views at stage 13, 15, 17, and 19. (B) Lateral view stage 13. (D, F) Dorsal view stage 15 and 17. (H) Lateral view stage 19. (I, K) Lateral and dorsal views, stage 24. (J, L) Lateral view of head staining, stages 32 and 34. (M) Lateral view stage 37. Embryos show staining in the anterior region of the embryo corresponding to the cement gland (yellow arrowhead). By stage 19, expression is also obvious bilaterally in the olfactory placode (black arrow), eye primordia (blue arrowhead), and in the trigeminal ganglia (red arrow). Dorsal and lateral views show expression in the Rohon–Beard neurons (black arrowhead). In later stages, Id4 is expressed in the liver (marked with a yellow L), branchial arches (black b), kidney (red arrowhead marks tubules in J, L, and M, red arrow marks duct in M), and in migrating melanophores (small red arrowheads in M).
