Fig. 2.

Labeled melanocyte clones extend proximo-distally in the caudal and anal fins. (A) fTyrp>GFP lineage transposon (Zou et al., 2006) was injected into one- or two-cell embryos, which were reared to maturity prior to screening for melanocyte clones in fins. (B,C) Examples of labeled melanocyte clones in center stripe, of caudal fin (B), and anterior 4 fin rays, of anal fin (C). White arrowheads indicate GFP^– melanocytes; green arrowheads indicate GFP⁺ melanocytes; broken white lines show outer boundaries of clones. Scale bars: 0.5 mm.
