Implication of scAAV2-GFP for labeling CST axons after injury.

<p>Dorsal column lesion resulted in a corresponding loss of CST axons, as visualized by anterograde transport of scAAV2-GFP at 4 weeks after viral injection into the sensorimotor cortex (A and C). GFAP staining of the section was to label the lesion site and cavity (B and E). Low magnification images shown in A–B, Corresponding high-magnification images shown in D–F. Scale Bars: 500 µm (A–C), 200 µm (D–F).
