Expression of <i>kitlga</i> promotes differentiation of new melanocytes in the stump.

<p>A-A’. At the time of amputation and prior to induction of <i>kitlga</i>, melanocytes are well organized and form the proximal portion of the dorsal melanocyte stripe of the caudal fin (yellow trapezoid). B-B’. Following 7 days of <i>kitlga</i> expression, new melanocytes are visible both in the regenerate (brackets) as well as in the stump (grey arrowheads) in association with the dermal fibroblast clone. Red dashed lines indicate the amputation plane. Scale bar = 250 mm.
