Impaired patterning of medial body surface in the Mesp quadruple mutant. In wild-type embryos, the lateral line has been deposited at the medial surface of the trunk and tail region at 2dpf (A). In contrast, the lateral line patterning is impaired in the Mesp quadruple mutant (B). In wild-type embryos, the melanocytes have elongated along the A-P axis and aligned themselves at the medial surface of the trunk and tail at 4dpf (C). In contrast, in the Mesp quadruple mutant embryo, the melanocyte morphology and alignment have been disrupted (D). Unlike the case for the wild-type larva, in which the iridophores are aligned along the mediolateral body surface (E), a gap has formed in the aligned iridophores in the Mesp quadruple mutant at 30dpf (F).
