Despite an absence of the regenerative outgrowth, dob mutant fins normally induce careg:EGFP in the amputation-activated stump.
(a-f) Live-imaging of careg:EGFP fins at 1 dpa in a wild-type (wt) background treated with DMSO or SB431542, and in the fgf20a (dob) mutant background. careg:EGFP expression is suppressed in the stump by the inhibition of TGFβ/Activin-β signaling, but it remains normal in fgf20a mutant fins. N=4.
