WebIn humans, axons of the peripheral nervous system (PNS) are capable of regeneration, whereas those of the central nervous system (CNS) are currently viewed as incapable of regeneration. This inability of the CNS to regenerate poses significant issues for the treatment of injury and disease of the nervous system.

Unlike peripheral nervous system injury, injury to the central nervous system is not followed by extensive regeneration. It is limited by the inhibitory influences of the glial and extracellular environment.
