Curr Drug Deliv:新型生物活性玻璃支架可有效恢复颅骨缺损

2019-06-15 不详 网络

在骨组织工程领域,对具有高血管生成能力和成骨能力的生物医学材料越来越感兴趣。在各种成骨材料中,生物活性硼硅酸盐和硼酸盐玻璃支架具有合适的降解速率和机械强度,因而引起了许多学者的兴趣和关注。在这项研究中,我们使用模板法制备了由硼硅酸盐2B6Sr组成的生物活性玻璃支架,并掺入了具有良好血管生成能力的小分子血管生成药物二甲基肟基甘氨酸(DMOG),以改善骨再生。体外研究表明,多孔硼硅酸盐生物活性玻璃支架

在骨组织工程领域,对具有高血管生成能力和成骨能力的生物医学材料越来越感兴趣。在各种成骨材料中,生物活性硼硅酸盐和硼酸盐玻璃支架具有合适的降解速率和机械强度,因而引起了许多学者的兴趣和关注。

在这项研究中,我们使用模板法制备了由硼硅酸盐2B6Sr组成的生物活性玻璃支架,并掺入了具有良好血管生成能力的小分子血管生成药物二甲基肟基甘氨酸(DMOG),以改善骨再生。

体外研究表明,多孔硼硅酸盐生物活性玻璃支架释放缓慢,稳定的DMOG,并刺激人骨髓基质细胞hBMSCs的增殖和成骨分化。体内研究表明,硼硅酸盐生物活性玻璃支架可显着促进大鼠颅骨缺损中的新骨形成和新生血管形成。

综上所述,这些结果表明,掺入DMOG的生物活性玻璃支架是一种具有优良血管生成-成骨能力的成功化合物,具有良好的临床应用前景。
