Chondroitin sulfate proteoglycans (CSPGs) are the most abundant components of glial scar formed after severe traumatic brain injury as well as spinal cord injury and play a crucial inhibitory role in axonal regeneration by selective contraction of filopodia of the growth cone of sprouting neurites. Healing of central nervous system (CNS) injury requires degradation of the glycosamine glycan backbone of CSPGs in order to reduce the inhibitory effect of the CSPG layer. The key focus of this Viewpoint is to address a few important regenerative approaches useful for overcoming the inhibitory barrier caused by chondroitin sulfate proteoglycans.
