Sci Rep:3D打印CSH/MBG支架或可有效促进骨再生

2018-01-23 MedSci MedSci原创

在临床上,由感染、创伤、手术切除和遗传畸形引起的骨缺陷仍然是重大挑战。在骨组织工程领域,三维(3D)支架有望用于治疗骨缺损。本研究采用3D打印技术,成功制备了水合硫酸钙(CSH)/介孔生物活性玻璃(MBG)支架,支架具有规则均匀的方形大孔结构,孔隙度高,磷灰石矿化能力优良。在支架上培养人骨髓间充质干细胞(hBMSCs)以评估hBMSCs的附着、增殖和与成骨相关的基因表达。使用临界尺寸的大鼠颅骨缺损

临床上,由感染、创伤、手术切除和遗传畸形引起的骨缺陷仍然是重大挑战。在骨组织工程领域,三维(3D)支架有望用于治疗骨缺损。

本研究采用3D打印技术,成功制备了水合硫酸钙(CSH)/介孔生物活性玻璃(MBG)支架,支架具有规则均匀的方形大孔结构,孔隙度高,磷灰石矿化能力优良。在支架上培养人骨髓间充质干细胞(hBMSCs)以评估hBMSCs的附着、增殖和与成骨相关的基因表达。使用临界尺寸的大鼠颅骨缺损模型来研究CSH/MBG支架对体内骨再生的影响。

体外实验结果显示,CSH/MBG支架可刺激hBMSCs的粘附,增殖、碱性磷酸酶(ALP)活性和成骨相关基因的表达。体内实验结果显示,与CSH支架相比,CSH/MBG支架可明显增强颅骨缺损处的新骨形成。

综上所述,该研究结果表明,3D打印的CSH/MBG支架或是促进骨再生的一种具有前景的支架材料。
