  Fig. 7. Early inhibition of TGF-β signaling prevents subsequent activation of the BMP signaling pathway in the regeneration bud. Regenerates treated with 100 μM SB-431542 or 0.2% DMSO from 0 to 8 hpa were harvested at 2 dpa and processed for the following markers: (A) immunofluorescence against phospho-Smad1 (p-Smad1, green), showing that p-Smad1 in the regeneration bud proper is eliminated by SB-431542 treatment. p-Smad1 (blue) in unamputated stage-matched tadpole tails was unaffected by SB-431542 (bottom row); (B) in situ hybridization with xMsx1 antisense probe (purple)—black arrow: xMsx1 expression in the dorsal blastema; (C) immunofluorescence for the mitotic marker phospho-Histone H3 (pH3, green). Total DNA in panels A and C is shown in blue. Arrowheads: amputation plane. Scale bar: 100 μM.
