Melanocyte Regeneration in Adult Zebrafish Requires mitfa-Expressing Cells

(A) Strategy for identifying cells that mediate melanocyte regeneration: promoter-based ablation of only differentiated melanocytes results in regeneration (left) whereas promoter-based ablation of differentiated melanocytes and cells that mediate melanocyte regeneration causes failure of regeneration (right).

(B) Adult zebrafish expressing mitfa:NTR in miniCoopR-rescued melanocytes and lineally related cells (top). Differentiated melanocytes were ablated upon Mtz treatment (middle) but failed to regenerate after Mtz was washed out (bottom). n = 5 fish; representative images are shown. mC, miniCoopR. Scale bar, 5 mm.

(C) Adult p53(lf) zebrafish expressing miniCoopR-mitfa:NTR (top). Differentiated melanocytes were ablated on Mtz treatment (middle), and new melanocytes regenerated after Mtz was washed out (bottom). n = 5 fish; representative images are shown. mC, miniCoopR. Scale bar, 5 mm.
