Melanocyte loss in p53 mutants. Fish were treated for 1 day in 750 nM NCP and washed into fresh water for 2 days. WT (A, C) and p53 mutants (B, D) are equally affected by the NCP treatment. The melanocytes have already fragmented and begun to be cleared (C, D). Scale bars in (A, B) are 500 μm and in (C, D) are 100 μm.
