J Endod:评估移植入小鼠体内的人牙髓干细胞的生物学分布

2018-02-04 lishiting MedSci原创

有些研究已经尝试了在体外利用人的牙髓干细胞(hDPSCs)来完成牙髓-牙本质复合体的再生。然而,在它们应用于临床试验前,首先需要评估其体内的安全性。因此,这篇研究的目的是为了评估移植牙髓内hDPSCs的体内最终命运。

有些研究已经尝试了在体外利用人的牙髓干细胞(hDPSCs)来完成牙髓-牙本质复合体的再生。然而,在它们应用于临床试验前,首先需要评估其体内的安全性。因此,这篇研究的目的是为了评估移植牙髓内hDPSCs的体内最终命运。研究从阻生的第三磨牙中分离并培养hDPSCs。体内试验使用7周龄的雄性BALB/c裸鼠。在深度麻醉后,使用静脉注射将1 × 105个hDPSCs通过尾部静脉移植入裸鼠体内或直接移植牙髓腔来完成牙髓内移植。研究共使用56只裸鼠,每组28只。试验动物在不同的时间节点处死,定量评估组织器官内的hDPSCs数量。另外,对移植牙髓内的hDPSCs进行定性评估。结果显示,在所有的时间节点,通过静脉注射的hDPSCs主要分布于肺,而在其他器官内几乎检测不到。随着时间的推移,移植入牙髓腔的hDPSCs几乎无法迁移至其他器官内。结论:这些数据表明,通过静脉和髓腔内移植的hDPSCs具有不同的分布,并且移植髓腔内的hDPSCs表现出良好的安全性。原始出处:Kim S, Lee S, et al.
