Promising repair strategies that may be combined to enhance CNS regeneration

1.	Protecting neurons and axons from secondary injury
2.	Elevating intrinsic capacity of injured CNS axons to regenerate
3.	Bridging the lesion gap with permissive cellular transplants and adhesion molecules
4.	Reducing glial scar formation and deposition of chondroitin sulfate proteoglycans
5.	Overcoming CNS myelin-associated inhibitors
6.	Enhancing directional growth with neurotrophic factors
7.	Enabling reinnervation of denervated targets
8.	Retraining the nervous system to use the therapeutic interventions
