  Fig. 4. mRNA expression of X. laevis Id2 (A–D), Id3 (E–H), and Id4 (I–L). Yellow lines mark plane of section. (A, E, I) Both Id2 and Id3 are expressed in the nasal pit (blue arrowhead) and in the otic vesicle (left of asterisk). Migrating cells (small red arrowheads) mark ventrally migrating muscle cells in (A) (Id2), the leading edge of migrating muscle cells in (E) (Id3), and migrating melanophores in (I) (Id4). (D, H, L) Id2 is expressed in both the dorsal and ventral portions of the myotome, in a region corresponding to the nuclei of the muscle cells (D–M). Id3 is expressed in the most dorsal and ventral portions of the myotome (H–M). Id4 is expressed weakly in a similar pattern to Id2. Both Id2 and Id3 are expressed in punctate cells in the fin mesenchyme. Id4 is not expressed in the fin mesenchyme. (The chordoneural hinge is marked with a red arrowhead, the inner fin with an open yellow arrowhead and the outer fin with a closed yellow arrowhead.) Id4 is also expressed in the lateral line (io: infraorbital, a: aortic) marked in (I).
