| 摘 要： | 目的研究气电纺聚羟基丁酸酯poly（3-hydroxybutyrate）,PHB]纳米纤维支架的体外生物相容性。方法实验组用PHB纳米纤维支架接种大鼠骨髓基质细胞进行体外培养,对照组用培养板培养孔接种大鼠骨髓基质细胞进行体外培养,通过扫描电镜、四甲基偶氮唑盐比色法以及碱性磷酸酶（alkaline phosphatase,ALP）检测来评价PHB纳米纤维支架对大鼠骨髓基质细胞粘附、增殖活性以及ALP活性的影响。结果气电纺PHB纳米纤维支架材料对大鼠骨髓基质细胞具有良好的亲和性;与细胞培养板相比,气电纺PHB纳米纤维支架材料上的大鼠骨髓基质细胞具有较高的增殖活性及ALP活性。结论气电纺PHB纳米纤维支架有望用作骨组织工程支架材料。
