The fibroblast growth factor (FGF) signalling pathway specifies the fate of pigmented cells in the ascidian Ciona intestinalis. Here, the authors obtain lineage-specific transcription profiles of pigment precursor cells and identify FGF downstream genes involved in central nervous system patterning, and the specification and differentiation of pigmented cells.
