Fig. s1 How to draw dotted lines outlining the circumference of pectoral fins. Pectoral fins of sox10:DsRed zebrafish (SL: 6.4). (A, B, C) The same samples as in Fig. 4A. (D, E, F) The same sample as in Fig. 4G. (A, D) Bright field photos of pectoral fins with high contrast for visualizing the circumference. White arrowheads indicate circumference of the pectoral fin. (B, E) Merged photos of bright field and sox10:DeRed with black dotted lines drawn along the circumference. (C, F) Bright field photos removed and only sox10:DsRed photos with white dotted lines for the circumference are shown. Scale bar: 200 μm in A.
