Nanoscale Res Lett:PDGF-加载的CS-Fb纳米纤维支架敷料可增强伤口愈合

2018-05-06 MedSci MedSci原创

伤口愈合是一个非常复杂的过程,需要各种生长因子和细胞的相互作用。尽管生物材料的研发不断取得进步,但只有少数具有生物活性的伤口敷料达到临床使用要求。本研究旨在探究静电纺丝制备的能够持续释放血小板衍生生长因子(PDGF)的新型纳米纤维壳聚糖(CS)纤维蛋白原(Fb)支架在促进成纤维细胞迁移和伤口愈合中的可行性。 使用双喷丝头静电纺丝器成功制备CS-Fb支架,并评估其物理、化学和生物特性。结果显

伤口愈合是一个非常复杂的过程,需要各种生长因子和细胞的相互作用。尽管生物材料的研发不断取得进步,但只有少数具有生物活性的伤口敷料达到临床使用要求。本研究旨在探究静电纺丝制备的能够持续释放血小板衍生生长因子(PDGF)的新型纳米纤维壳聚糖(CS)纤维蛋白原(Fb)支架在促进成纤维细胞迁移和伤口愈合中的可行性。

使用双喷丝头静电纺丝器成功制备CS-Fb支架,并评估其物理、化学和生物特性。结果显示,与单独组分静电纺丝的纳米纤维相比,CS-聚乙/Fb支架的纤维直径更小,同时表现出足够的机械性能和均匀的聚合物分布。另外,支架在伤口愈合应用中表现出可接受的水转移速率。 PDGF成功并入支架并在整个静电纺丝过程中保持功能活性。此外,释放的PDGF可有效促进成纤维细胞迁移,相当于单次50ng/mL剂量的PDGF。

综上所述,该研究结果表明,PDGF-加载的CS-Fb纳米纤维支架或可作为增强伤口愈合的新型生物活性敷料。

Adv Mater:核酸适配体功能化的双面材料应用于膝关节修复

膝关节损伤是日常生活中常见的一类组织损伤性疾病,如果得不到及时有效治疗,将有可能造成肢体残疾的严重后果。目前,将外源干细胞移植入体内再刺激其定向分化从而实现膝关节修复已经成为研究的热点。但是,由于干细胞不具备靶向识别作用且而导致其不能有效到达膝关节缺损部位,因此体外系统注射外源干细胞不能高效实现膝关节修复。除此之外,由于膝关节部位由软骨及软骨下骨两种具有不同的组成成分、代谢能力与再生能力的组织组成
