Figure Caption
Fig. S3 Dkk1b overexpression suppresses injury-dependent cell proliferation. (A) Heat shock in hs:Dkk1GFP fish, but not Wt fish, stimulates Dkk1b–GFP fusion protein expression in the retina and inhibits fin regeneration. Arrows in fin panels indicate the amputation plane. (B) Heat shock in hs:Dkk1GFP fish, but not Wt fish, inhibits injury-dependent MG proliferation. Asterisk indicates the injury site. (Scale bar, 50 μm.) dpa, days post amputation; INL, inner nuclear layer.
