Regeneration of transected dorsal root ganglion cell axons into the spinal cord in adult frogs (Xenopus laevis).

The extent of regeneration of the central axonal processes of dorsal root ganglion cells was determined using anterograde horseradish peroxidase histochemistry at 1-12 weeks after dorsal root transection in adult frogs. At 4, 8 and 12 weeks axons were found to have regenerated across the dorsal root entry zone and into the spinal cord.
