Systemic artemin administration increases retrodgrade labeling of DRG neurons from the dorsal horn. The tracers CTB or rhodamine-dextran were injected into the dorsal horn ipsilateral to surgery 11 d following DRC or sham injury and immediate treatment with six subcutaneous injections of artemin or vehicle. Fluorescence labeling is shown in DRG on day 14 after surgery. Scale bar represents 125 µm.
