组织工程化神经研究进展

近年来,组织工程化周围神经研制工作取得了很大的进展。自体神经、同种异体神经和合成材料均可作为桥接神经缺损的神经导管,以化学萃取的同种异体神经及可降解的生物材料导管较为理想。同时,经培养和纯化后的雪旺细胞具有分泌多种神经营养因子活性,是提高修复神经损伤效果的关键。

The Advancement of Nerve with Tissue Engineering Technique

Great progress was made on the study of peripherial nerve with tissue engineering technique in recent years. Allogeneic nerve grafts,heterogenous nerve grafts and synthetic materials are all nerve duct that bridge grafting neurologie defeat,in which the chemical extraction heterogenous nerve and the biodegradable nerve graft duct are the ideal materials. In addition, cultured and purified Schwann cells play a key role in promoting the repair efficacy of nerve injury because of its ability to secrete numerous neurotrophic factors.
