Fig. 5 Fgfr1 inhibition blocks msx gene expression in the fin regenerate. (A, B) Fins from untreated fish (A) and Ri-treated fish (B) stained for β-catenin mRNA expression at 24 h postamputation (arrowheads mark signals). Arrows demarcate amputation plane in each photograph. (C, D) Fins from Ri-treated fish assessed for msxb (C) or msxc (D) expression at 24 h postamputation. Wound epidermal β-catenin expression was normal in Ri-treated fish, but expression of mesenchymal msxb and msxc was very low or absent (compare with Figs. 2E and 2I). Original magnification was 50x.
