Polydopamine-modified chitin conduits with sustained release of bioactive peptides enhance peripheral nerve regeneration in rats
[INLINE:1] The introduction of neurotrophic factors into injured peripheral nerve sites is beneficial to peripheral nerve regeneration.However, neurotrophic factors are rapidly degraded in vivo and obstruct axonal regeneration when used at a supraphysiological dose, which limits their clinical benefits.Bioactive mimetic peptides have been developed
