Wnt production is required for fin regeneration. Regeneration of caudal fins from Tg(sp7:EGFP) fish exposed to DMSO (upper panels) or 10 μM IWP-2 (lower panels) from 0-8 dpa. Each animal is shown before amputation and at 2, 4, and 8 dpa by Rotterman contrast and epifluorescence to visualize sp7:EGFP expression (green) in osteoblasts at 25x and at 120x magnification. Shown is one of three fish from each treatment group, within which phenotypes were indistinguishable. The experiment was repeated with three independent fish cohorts.
