摘要:

文题释义:

细胞外基质:细胞外基质是器官和组织以及细胞附着、分化、增殖和迁移的独特支持结构,其可调控细胞的多种行为。同时,细胞外基质还是生长因子的储存库,其多种成分可结合并调控生长因子的活性。

生长因子递送系统:是指在时空和剂量上可对生长因子在生物体内分布进行全面调控的技术体系,其目标是在合适的时机将适量的生长因子递送到所需要的位置,增加生长因子的生物利用度,提高疗效和降低成本的同时并减少不良反应。

 

摘要

背景:生长因子的局部应用为难愈性骨缺损治疗提供了很有前景的治疗策略,但其仍存在诸多限制因素,如无法精确控制生长因子的释放量及生长因子释放后生物活性较低等,因此生长因子递送系统的改良是亟待解决的问题。

目的:总结多种包含细胞外基质成分的生长因子递送系统及其在骨缺损治疗方面的最新研究进展。

方法:由第一作者以extracellular matrixintegrinsheparingrowth factorcontrolled delivery systembone defect,细胞外基质,整合蛋白,肝素,生长因子,缓释系统,骨缺损”为关键词,检索20072019年期间PubMedWeb of ScienceMedline、万方、CNKI数据库中的相关文献。初检文章317篇,筛选后对59篇文章进行分析。

结果与结论:细胞外基质成分可结合并调控生长因子的活性,提高其生物利用度。因此将细胞外基质成分整合入生长因子递送系统中可达到对生长因子递送系统的改良。与普通生长因子递送系统相比,细胞外基质性生长因子递送系统可以获得更好的生长因子结合效果,更高的生物活性与利用度,甚至更好的靶向性释放,产生更好的促进骨再生的治疗效果。因此细胞外基质性生长因子递送系统为难愈性骨缺损局部治疗提供了更优良的治疗策略。

Abstract:

BACKGROUND: The local application of growth factor provides a promising therapeutic strategy for the treatment of refractory bone defects. However, there are still many factors that limit the application of the local growth factor delivery system, for example, inability to accurately control the amount of growth factors released and the low biological activity of the released growth factors.


OBJECTIVE: To summarize a variety of growth factor delivery systems containing extracellular matrix components and the latest research progress regarding their application in the treatment of bone defects.

METHODS: The first authors searched PubMed, Web of Science, Medline, Wanfang and CNKI databases to retrieve articles published during 2007-2019 with the search terms “extracellular matrix, integrins, heparin, heparin, growth factor, controlled delivery system, bone defect” in English and Chinese, respectively. A total of 317 articles were initially retrieved, and 59 of them were included in the final analysis.

RESULTS AND CONCLUSION: Extracellular matrix components can combine and regulate the activity of growth factors and improve their bioavailability. Therefore, improvement of growth factor delivery system can be achieved by integrating extracellular matrix components into the growth factor delivery system. Compared with the common growth factor delivery system, the extracellular matrix growth factor delivery system can obtain better growth factor binding effect, higher biological activity and utilization, and even better targeted release, thus producing better effects on promoting bone regeneration. Therefore, the extracellular matrix growth factor delivery system provides a better therapeutic strategy for local treatment of refractory bone defects.

Key words: extracellular matrix, integrin, heparinization, growth factor, local delivery system, bone defect, scaffold, bone tissue engineering
