摘要:
为了模拟自然骨的成分以及进一步提高材料的生物活性,制备羟基磷灰石@壳聚糖@明胶和锶磷灰石@壳聚糖@明胶复合支架,并对两种材料的生物性能进行表征。通过同轴电纺制备核壳结构的壳聚糖@明胶纤维;并采用化学沉积方法,在壳聚糖@明胶纤维表面沉积羟基磷灰石或锶磷灰石颗粒。结果显示:沉积锶磷灰石后,支架仍然能保持利于细胞生长的网状结构;细胞毒性实验和增殖实验结果表明,MG63细胞在支架材料上的存活率均超过70%;与羟基磷灰石@壳聚糖@明胶复合支架相比,锶磷灰石@壳聚糖@明胶复合支架的细胞存活率更高,表明该材料确实促进细胞的生长和活性。因此锶磷灰石@壳聚糖@明胶复合支架有良好的骨组织工程应用前景。
