| 1 | 周围神经损伤与再生:新型修补材料的应用研究与进展显示文摘背景:虽然自体神经移植是当前治疗大段神经缺损的金标准,但因其应用受到诸多限制,因此科学家从未放弃探索新型神经修补材料。目的:回顾近年来周围神经损伤领域产生的新观点、再生过程中的关键细胞及新型神经导管的应用。方法:由第一作者检索2001至2016年Pub Med数据库收录的与组织工程神经支架材料相关的文献,检索词为'peripheral nerve injury,peripheral nerve regeneration,nerve scaffold',按纳入、排除标准最后共纳入文献76篇进行综述。结果与结论:周围神经的修复主要集中在如何让再生的神经长得'快'与长得'准'上,未来除了应继续拓展开发生物相容性更好的材料外,还应优化设计,在分子细胞和组织层面多层次模拟神经再生微环境,模拟建立取向纳米结构、化学组分、生物信号时空分布等多重仿生神经移植物。应明确的是,神经导管不应只是简单的力学支撑,还应具有一定功能,如导电、细胞因子梯度缓释等。仿生也不应只局限于形态学上,还应拓展到如细胞因子的时空变化、细胞生物电刺激等方面上来。 | 全琦 苌彪 刘若西 孙逊 王玉 卢世璧 彭江 赵庆 | 2017 | 中国组织工程研究2017，21，6： | 15 |
| 2 | Dental pulp stem cells and BonelikeVR for bone regeneration in ovine model显示文摘Development of synthetic bone substitutes has arisen as a major research interest in the need to find an alternative to autologous bone grafts.Using an ovine model,the present pre-clinical study presents a synthetic bone graft(BonelikeVR)in combination with a cellular system as an alternative for the regeneration of non-critical defects.The association of biomaterials and cell-based therapies is a promising strategy for bone tissue engineering.Mesenchymal stem cells(MSCs)from human dental pulp have demonstrated both in vitro and in vivo to interact with diverse biomaterial systems and promote mineral deposition,aiming at the reconstruction of osseous defects.Moreover,these cells can be found and isolated from many species.Non-critical bone defects were treated with BonelikeVR with or without MSCs obtained from the human dental pulp.Results showed that BonelikeVR and MSCs treated defects showed improved bone regeneration compared with the defects treated with BonelikeVR alone.Also,it was observed that the biomaterial matrix was reabsorbed and gradually replaced by new bone during the healing process.We therefore propose this combination as an efficient binomial strategy that promotes bone growth and vascularization in non-critical bone defects. | J.M.Campos A.C.Sousa A.R.Caseiro S.S.Pedrosa P.O.Pinto M.V.Branquinho I.Amorim J.D.Santos T.Pereira C.M.Mendonca A.Afonso L.M.Atayde A.C.Maurı´cio | 2019 | Regenerative Biomaterials2019，6，1： | 0 |
