The role of extracellular matrix in CNS regeneration

Abstract

Chondroitin sulfate proteoglycans are the principal inhibitory component of glial scars, which form after damage to the adult central nervous system and act as a barrier to regenerating axons. Recent findings have furthered our understanding of the mechanisms that result in a failure of regeneration after spinal cord injury and suggest that a multipartite approach will be required to facilitate long-distance regeneration and functional recovery.
