摘要
脊髓损伤(SCI)是一种常见的神经功能障碍性疾病,它将导致感官功能和移动性的丧失。组织工程学是一个潜在的治疗脊髓损伤的治疗策略,这是有据可查的。在这一点上,各种各样的生物材料已经被开发出来以满足脊髓损伤组织工程的需要,这包括天然材料,合成生物降解高分子和合成非降解聚合物。纳米纤维支架是最近新兴的被广泛应用于组织工程的生物材料。与传统的生物材料相比,纳米纤维在拓扑结构和孔隙率方面具有优势,从而能够模仿天然细胞外基质。另外,它们显示了极好的生物相容性和低的免疫原性,此外它们具有能够帮助弥合病变腔或者孔隙的特性,且可作为移植细胞或者治疗药物的一种有效的运输递质系统。这篇综述总结了在治疗脊髓损伤方面具有至关重要的潜在应用的纳米纤维支架的一些独特的属性。

摘要: Spinal cord injury (SCI) is a common neurologic disorder that results in loss of sensory function and mobility. It is well documented that tissue engineering is a potential therapeutic strategy for treatment of SCI. In this connection, various biomaterials have been explored to meet the needs of SCI tissue engineering and these include natural materials, synthetic biodegradable polymers and synthetic non- degradable polymers. Nanofiber scaffolds are newly emerging biomaterials that have been widely utilized in tissue engineering recently. In comparison to the traditional biomaterials, nanofibers have advantages in topography and porosity, thus mimicking the naturally occurring extracellular matrix. Besides, they exhibit excellent biocompatibility with low immunogenicity, and furthermore they are endowed with properties that help to bridge the lesion cavity or gap, and serve as an effective delivery system for graft cells or therapeutic drugs. This review summarizes some of the unique properties of nanofiber scaffolds which are critical to their potential application in treatment of injured spinal cord.
