Melanophores extend long projections. (A,B) Black stripe region of wild-type fish in the normal condition (A) and after addition of yohimbine (B), which reveals projections extending towards xanthophores. (C) Regions imaged in D-F. (D-F) Fluorescent images of melanophore membranes revealed by mitfa: EGFP-CAAX expression in brassb2 mutants. (D) Three melanophores in the black stripe extend long projections towards xanthophores. (E) A cluster of melanophores, each of which exhibits long projections. (F) Melanophores adjacent to a break in the stripe extend long projections radially. Scale bars: 100 μm. |
