BMP receptor signaling is required for regeneration. Regeneration of caudal fins from Tg(sp7:EGFP) animals exposed to DMSO (upper panels) or BMPRi (lower panels, 5 μM at 0-8 dpa). Images show the progression of regeneration in an individual fish before amputation and at 2, 4, and 8 dpa using Rotterman contrast and epifluorescence to visualize sp7:EGFP expression (green) in osteoblasts at 25x and 120x magnification. One of three fish, which all behaved similarly, from the two treatment groups are shown. The experiment was repeated using three independent sets of animals.
