这篇研究的目的是通过纳米生物活性玻璃(nBG)诱导原发性牙本质上的干细胞定向迁移和成牙本质分化,这对于功能性牙髓牙本质复合体的再生十分重要。

这篇研究的目的是通过纳米生物活性玻璃(nBG)诱导原发性牙本质上的干细胞定向迁移和成牙本质分化,这对于功能性牙髓牙本质复合体的再生十分重要。

研究对人的骨髓间充质干细胞(BMSCs)施以0.5 mg/mL nBG诱导培养。通过IncuCyte S3 live cell imaging system (Essen BioScience, Ann Arbor, MI)监控细胞和生物材料之间的相互作用。分别在2小时和3天观察BMSCs在nBG镀层的牙本质上生长的附着和形态。通过3维胶原凝胶模型检测nBG镀层的牙本质对BMSCs的趋药效应。将nBG镀层牙本质片植入裸鼠皮下以体内检测细胞归巢和成牙本质分化。

结果显示,nBG颗粒显示出良好的生物相容性,它们逐渐降解并在与BMSCs相互作用过程中重新附着。BMSCs在nBG镀层牙本质上的附着能力明显优于未处理牙本质组。细胞迁移试验显示,nBG镀层牙本质比未处理组能诱导更多细胞迁移。体内研究显示,nBG镀层牙本质推进根管内的再细胞化和血管再生,并且在原发性牙本质表面能够检测到DSPP表达阳性的细胞。

结论:nBG能够募集干细胞移动至牙本质,并且进一步促进原发性牙本质上细胞的粘附和成牙本质分化,这有助于再生牙髓牙本质复合物的仿生结构。
