DiI labeling at a distance of 2 mm from the cut on days 2 (a, a’), 16 (b, b’), and 25 (c) after labeling and injury. The site of dye application is indicated by an arrow. The radial nerve cord is outlined by dotted lines. Dashed lines show the original wound magins. (a’) and (b’) are higher magnification views of the boxed regions in a and b, respectively. d Uninjured radial nerve cord 25 days after labeling
