Med Sci Monit:丝素蛋白/壳聚糖/明胶可用于骨组织工程

2017-12-02 MedSci MedSci原创

骨组织工程是治疗骨缺损的有力工具,高度依赖于支架的使用。丝素蛋白(SF)和壳聚糖(Cs)具有良好的生物相容性,在组织工程重建中的应用得到越来越多的关注。明胶(Gel)由于其低抗原性和物理化学稳定性而在生物医学领域广泛应用。在这项研究中,研究人员构建了4种不同类型的支架:SF,SF/Cs,SF/Gel和SF/Cs/Gel,比较了它们的物理和化学性质,并对其进行生物学表征以确定最适合用于骨再生的支架。

骨组织工程是治疗骨缺损的有力工具,高度依赖于支架的使用。丝素蛋白(SF)和壳聚糖(Cs)具有良好的生物相容性,在组织工程重建中的应用得到越来越多的关注。明胶(Gel)由于其低抗原性和物理化学稳定性而在生物医学领域广泛应用。

在这项研究中,研究人员构建了4种不同类型的支架:SF,SF/Cs,SF/Gel和SF/Cs/Gel,比较了它们的物理和化学性质,并对其进行生物学表征以确定最适合用于骨再生的支架。首先,通过化学交联方法和冷冻干燥技术来制备这些支架。接下来,使用扫描电子显微镜研究内部结构的表征,并且通过液体置换法评估孔隙率。然后,比较吸水率和降解性等理化性质。最后将MC3T3-E1细胞接种于支架上,体外研究三维支架的生物相容性和成骨能力。结果显示,SF/Cs/Gel复合支架最适用于骨再生。

总之,该研究结果表明,在4种适合骨再生的支架中,SF/Cs/Gel支架最适合骨再生,或是用于治疗骨缺损或骨折骨再生的新选择。
