Enteric glia promote regeneration of transected dorsal root axons into spinal cord of adult rats

After spinal cord injury axonal regeneration is poor, but may be enhanced by the implantation of olfactory ensheathing glia (OEG). Enteric glia (EG) share many properties of OEG. Transected dorsal root axons normally do not regenerate through the central nervous system myelin into the spinal cord. We tested whether EG, like OEG, could promote regeneration in this paradigm. Three weeks after EG implantation, numerous regenerating dorsal root …
