Staining for Lef1 in longitudinal sections after amputation of denervated fins. Lef1 protein is detected in the BEL of both control and denervated fins from 0.5 to 2 dpa. At 0.5 dpa Lef1 expression is similar in control (a) and denervated (b) fins. At 2 dpa Lef1 is restricted to the most proximal BEL cells in control fins (c-arrowhead) and it is expressed all over the BEL lining mesenchymal cells of denervated fins (d-arrowhead). Scale bar - 25 µm. a-d) The images are a projection of confocal optical slices. Dashed lines mark amputation plane. Scale bar - 25 µm.
