摘要
Conventional vs. polyethylene glycol （PEG）-fusion tech- nologies to repair severed spinal axons： Most spinal cord injuries （SCIs） involve cutor crush-severance of spinal tract axons in the central nervous system （CNS）. Clinical out- comes after CNS axonal severance is very poor because proximal segments of CNS axons lack a suitable environment for outgrowth （Kakulas, 1999; Fitch and Silver, 2008; Rowland et al., 2008; Kwon et al., 2010） and therefore do not naturally regenerate （Ramon y Caial, 1928）. Current strategies to try to increase behavioral recovery after SCI are focused on en- hancing the environment for axonal outgrowth.
