最近的研究表明,复合生物材料形成的水凝胶比单一生物材料形成的水凝胶是组织修复的更好选择。利用丝素蛋白(SF)和丝胶蛋白(SS)优异的机械性能以及SS的细胞粘附和生物相容性特性,探讨了丝素蛋白(SF)和丝胶蛋白(SS)形成的复合水凝胶在组织修复中的可行性。在我们的研究中,SF SS 水凝胶是由 SF 和 SS 蛋白采用单独提取方法(LiBr 溶解 SF,热碱水溶解 SS)形成的,而 SF-SS 水凝胶是由 SF 和 SS 蛋白采用同时提取方法(LiBr 溶解 SF 和 SS 蛋白)形成的。分析了两种复合水凝胶对巨噬细胞和伤口释放炎症细胞因子的影响。此外,两种水凝胶被用来封装和递送人脐带间充质干细胞衍生的外泌体(UMSC-Exo)。 SF SS 和 SF-SS 水凝胶均可促进伤口愈合、血管生成,并减少炎症和巨噬细胞的 TNF-α 分泌。这些有益效果在采用 SF-SS 水凝胶封装的 UMSC-Exo 治疗的实验组中更为显着。我们的研究发现,SF-SS 水凝胶可以作为传递外泌体进行组织修复的绝佳替代品。
Recent studies have shown that the hydrogels formed by composite biomaterials are better choice than hydrogels formed by single biomaterial for tissue repair. We explored the feasibility of the composite hydrogel formed by silk fibroin (SF) and silk sericin (SS) in tissue repair for the excellent mechanical properties of SF, and cell adhesion and biocompatible properties of SS. In our study, the SF SS hydrogel was formed by SF and SS protein with separate extraction method (LiBr dissolution for SF and hot alkaline water dissolution for SS), while SF-SS hydrogel was formed by SF and SS protein using simultaneous extraction method (LiBr dissolution for SF and SS protein). The effects of the two composite hydrogels on the release of inflammatory cytokines from macrophages and the wound were analyzed. Moreover, two hydrogels were used to encapsulate and deliver human umbilical cord mesenchymal stem cell derived exosomes (UMSC-Exo). Both SF SS and SF-SS hydrogels promoted wound healing, angiogenesis, and reduced inflammation and TNF-α secretion by macrophages. These beneficial effects were more significant in the experimental group treated by UMSC-Exo encapsulated in SF-SS hydrogel. Our study found that SF-SS hydrogel could be used as an excellent alternative to deliver exosomes for tissue repair.
