Unilateral DiI labeling of the injured radial nerve cord, longitudinal sections. Immediately after bisection, the dye was applied to one side of the wound, while the opposite side was left unlabeled. The arrow shows the site of the original dye application. a On day 2 after the surgery, the dye remained on one side of the wound. (a’) Higher magnification of the boxed area in (a). b By day 25 after surgery, the wound gap is bridged and the two stumps of the radial nerve cord have reconnected across the wound gap. The dashed lines show the original wound margins. Note extensive migration of labeled cells into the new tissue bridging the wound gap. The dotted line marks the outline of the radial nerve cord
