Wnt Signaling Is Activated during Melanocyte Regeneration

(A) Flank of an adult zebrafish coexpressing mitfa:nlsEGFP and miniCoopR-TOPFlash:mCherry (top) or mitfa:nlsEGFP and miniCoopR-FOPFlash:mCherry (bottom). In animals with Tg(miniCoopR-TOPFlash:mCherry), mCherry signal was evident in differentiated melanocytes (white arrowheads) but not in unpigmented mitfa-expressing cells (yellow arrowheads). No mCherry signal was observed in Tg(miniCoopR-FOPFlash:mCherry) animals. Fish were treated with epinephrine prior to imaging. mC, miniCoopR; BF, brightfield. Scale bars, 100 µM.

(B) Lineage tracing of unpigmented mitfa-expressing cells on the flank of an adult zebrafish coexpressing mitfa:nlsEGFP and miniCoopR-TOPFlash:mCherry after neocuproine treatment. An unpigmented mitfa-expressing cell (yellow arrowheads) beginning to express mCherry shortly before differentiation (white arrowheads). mC, miniCoopR; BF, brightfield. Scale bar, 50 µM.
