Src causes non-autonomous tissue overgrowth. (A–D) Eye-antennal discs (A, A′, C and C′) and eyes (B, B′, D and D′) of adult flies bearing GFP-labelled wild-type (A, A′, B and B′) or Src64B-expressing (C, C′, D and D′) clones are shown. Cell nuclei were stained with DAPI (blue) (A′ and C′). Clones were visualized by GFP fluorescence in the adult (B′,D′). See supplementary Information online for genotypes. DAPI, 4,6-diamidino-2-phenylindole; GFP, green fluorescent protein; wt, wild type.
