摘要Peripheral nerve injury is a common disease that endangers human health.There is avariety of methods to repair peripheral nerve injury,the current "gold standard" approach is autograft,however it still faces many disadvantages.A new choice is the use of artificial nerve conduits,which are tubular structures and are designed to bridge nerve gaps.In order to bridge longer nerve gaps and gain ideal nerve regeneration effects,multiple technologies have been developed to the design of nerve conduits,such as selecting sutible materials,supplementing growth factors,transplanting supporting cells and so on.This review mainly introduce current progess in growth factors supplementation and supporting cells transplantation technology of nerve conduits.
