有效因子

Research of microenvironment werefocused on the neurotrophic factors. Many studies have been done to use nerve conduits filled with exogenetic NTFs with the intention of promote axonal regeneration to the greatest extent efficiently. However concentration of exogenetic NTFs and the means of releasing NTFs still need to be studied.
