BaTO3/P(VDF-TrFE)纳米复合膜对干细胞铺展与增殖的影响
|
Abstract:
摘要 目的:对比考察不同钛酸钡含量的BaTO3/P(VDF-TrFE)压电纳米复合膜对大鼠骨髓间充质干细胞粘附、铺展和增殖活性的影响,为优化电活性引导组织再生膜材料的生物学性能提供基础。方法:采用溶液浇铸法制备出含有不同钛酸钡纳米颗粒含量(0vol%、1vol%、3vol%、5vol%)的BaTO3/P(VDF-TrFE)压电纳米复合膜,通过扫描电镜、原子力显微镜和X-射线衍射仪对材料表面形貌和化学成分进行检测,采用铁电测试仪对材料的压电性能进行测试。取P3-P5代大鼠BMSCs于极化处理后的含有不同钛酸钡BTO含量的BaTO3/P(VDF-TrFE)压电纳米复合膜上常规培养,分别用扫描电镜和CCK-8法检测BMSCs的粘附铺展和增殖情况。采用SPSS13.0软件,运用单因素方差分析进行统计学分析。结果:压电纳米复合膜的压电性能呈现钛酸钡含量依赖性。结论:含有5vol%钛酸钡纳米颗粒的BaTO3/P(VDF-TrFE)压电纳米复合膜有利于促进BMSCs的粘附、铺展和增殖
