Figure 4. Axon regeneration inside the channels for different treatment conditions.
Images of an (a) empty bridge or a bridge loaded with a lentivirus encoding either (b) NT3 or (c) BDNF. Bridges were retrieved 4 weeks post implantation, and sections from the rostral position were stained with NF200 (neurofilament, brown). Channels are identified by the dash circles. Scale bar is 250 µm.
