摘要:

背景:神经损伤后没有自我修复的能力,因此,神经组织工程支架材料应用于神经修复、促进神经再生成为研究的热点。
目的:分析目前常用的神经组织工程支架材料的应用范围及效果。
方法:分别对胶原、壳聚糖、凝胶以及透明质酸与人工合成材料形成的聚合物用于神经损伤修复进行动物模型分析,应用免疫染色、生化检测等方法观察评估再生神经的结构和生理功能,确定不同神经组织工程支架材料的应用效果。
结果与结论:神经组织工程支架材料胶原、壳聚糖、凝胶、透明质酸以及人工合成材料均可以通过不同的方式用于损伤神经的再生修复,既可以联合细胞进行生物聚合,也可以联合神经片段移植形成损伤神经桥状联接导管,应用于动物模型实验均显示较好的治疗效果。

Abstract:

BACKGROUND: The injured nerve has no self-repair ability, therefore, nerve tissue engineering scaffolds have achieved increasing attention involving nerve repair and promotion of neural regeneration.
OBJECTIVE: To analyze the application and efficacy of the commonly used nerve tissue engineering scaffolds.
METHODS: The polymer materials which were consisted of collagen, chitosan, gelatin, hyaluronic acid and synthetic materials for the repair of nerve injury were explored in animal models. The structure and physiological functions of the regenerated nerve were observed with immunohistochemical staining and biochemical assay. Thus the application prospect of different nerve tissue engineering scaffolds was observed.
RESULTS AND CONCLUSION: Nerve tissue engineering scaffold materials, such as collagen, chitosan, gelatin, hyaluronic acid and synthetic materials, are all effective in the repair process of nerve injury and regeneration through different ways, they can combine with cells for a biological polymerization, also combines with nerve fragment transplantation to form bridge connecting conduit in the injured nerve, obtaining therapeutic effect in animal model experiments.
