Fig 3. Kctd15 mutant larvae have more xanthophores.

At 6 dpf, there are more mature xanthophores, as indicated by methylene blue staining (A); however, their appearance is just like WT (B). Examination of genes involved in xanthophore specification showed that there was an increase in abundance of gch2 transcripts at 25 hpf (C-E), most notably in the cranial pigment cells.
