Expression of X. helleri fgf24 during fin regeneration. fgf24 is expressed in the wound epidermis at 3 dpa (A, B). Expression diminishes after 3 dpa and is almost absent by 4 dpa (C, D). fgf24 is not differentially expressed in sword rays (B) compared to non-sword rays (A). White arrowheads indicate the expression in wound epidermis and white arrows the level of amputation. (3 dpa fgf24: n = 6; 4 dpa fgf24: n = 5; scale bars: 200 μm).
