摘要:

首先通过固相合成方法制备了含有壳聚糖特异性结合结构域(ChiBD)的成纤维细胞生长因子模拟肽(CFAP1), CFAP1中的ChiBD序列能够与壳聚糖材料特异性地结合; 随后将CFAP1与甲基丙烯酰化羧甲基壳聚糖(CCSMA)按优化的比例共混, 通过光固化法制备了一种新型创面修复水凝胶——CCSMA@CFAP1水凝胶. 研究结果表明, CCSMA@CFAP1水凝胶对大肠杆菌(E.coli)和金黄色葡萄球菌(S.aureus)的生长有明显的抑制作用, 并且具有突出的抗氧化特性. 同时, CCSMA@CFAP1水凝胶能够显著促进NIH-3T3成纤维细胞的黏附与增殖, 并上调细胞中Ⅰ型胶原蛋白(COL-1)和血管内皮生长因子(VEGF)的表达. 动物实验结果表明, CCSMA@CFAP1能够通过抑制过度炎症、 促进组织血管化和组织再生. 在修复264 h后, CCSMA@CFAP1组的伤口愈合率达到94.68%. 同时, CCSMA@CFAP1水凝胶具有良好的生物安全性. 本文研究结果可为相关材料在创面修复方面的应用提供理论和实践数据.

Abstract:

A fibroblast growth factor mimetic peptide(CFAP1) containing chitosan-binding domain(ChiBD) was first synthesized via the solid-phase synthesis method. The ChiBD sequence in CFAP1 enables specific binding to chitosan-based materials. CFAP1 was blended with carboxymethyl chitosan methacrylate(CCSMA) at an optimized ratio to fabricate a novel wound repair hydrogel through the photo-crosslinking approach. The results demonstrated that the CCSMA@CFAP1 hydrogel exerted a significant inhibitory effect on the growth of Escherichia coliE.coli) and Staphylococcus aureusS.aureus), and exhibited prominent antioxidant properties. Meanwhile, this hydrogel could remarkably enhance the adhesion and proliferation of NIH-3T3 fibroblasts, as well as upregulate the expression of Type Ⅰ Collagen(COL-1) and Vascular Endothelial Growth Factor(VEGF) in the cells. The results of in vivo study indicated that CCSMA@CFAP1 accelerated wound healing by suppressing excessive inflammation, promoting tissue vascularization. After 264 h of repair, the wound healing rate of the CCSMA@CFAP1 group reached 94.68%. Furthermore, the CCSMA@CFAP1 hydrogel possessed favorable biosafety profiles. Collectively, this research provides theoretical and experimental evidence for the application of related materials in wound repair.
