摘要: 目的:探讨明胶海绵作为体外成骨支架材料的可行性及BMP7对小鼠诱导型多能干细胞(miPSCs)在三维培养条件下骨向分化能力的影响。方法:miPSCs经体外培养形成拟胚体(EBs),将消化所得的单细胞于明胶海绵上成骨诱导,7 d后检测其成骨能力及贴附情况。结果:miPSCs可以贴附并沿着明胶纤维伸展;BMP7添加组的钙结节含量及成骨基因表达水平高于未添加组。结论:明胶海绵可以作为miPSCs体外成骨的培养支架;BMP7对三维培养条件下miPSCs的成骨能力有促进作用。

Abstract: Objective: To investigate the effect of BMP7 on the osteogenic differentiation ability of mouse iPSCs in the absorbable gelatin sponge scaffold. Methods: EBs induced from mouse iPSCs were digested into single cells and microinjected into the gelatin sponge. After 7 days of osteogenic induction, the osteogenic and adhesive abilities of the cells were examined. Results: Mouse iPSCs attached and spread along the gelatin sponge. Compared with the group without BMP7 treatment, the group treated with BMP7 had higher levels of deposited calcium and osteoblastic markers. Conclusion: Gelatin sponge can be used as cell culture scaffold for mouse iPSCs and BMP7 promotes osteogenesis of mouse iPSCs in the culture system.
