１　研究回顾　神经再生趋化性是指神经损伤后，再生轴突能够识别远端神经的性质，并朝相应的靶器官生长，这种作用被认为是由靶器官产生的诱导性蛋白成分所致。神经再生趋化性理论由Ｆｏｒｓｓｍａｎ于１８９８年最先提出。他发现离断神经的近侧断端总是向远侧断端生长，而不 1 Research Review Neuroregeneration Chemotaxis refers to the nerve injury, axonal regeneration can identify the nature of the distal nerve, and toward the corresponding target organ growth, this effect is considered to be induced by the target organ protein components caused . The theory of neuroregeneration chemotaxis was first proposed by Forssman in 1898. He found that the proximal stump of the severed nerve always grew distally to the distal part, not
