Fig. S1 Expression of msxC at 4 dpa using in situ hybridization on whole-mount fins 1 day after injection of EGFP (A, C) and chordin (B, D). msxC expression seen in the distal blastema of 2 fin rays (A) and on a higher magnification image of the domain of expression in the blastema of one ray indicated by an asterisk in (C), 1 day following EGFP injection. The expression is strongly reduced in the distal blastema 1 day following chordin injection as seen on 2 fin rays (B) and at a higher magnification of the distal blastema of the ray indicated by the asterisk in (D). Scale bars: (A, B) = 20 μm; (C, D) = 40 μm.
