Sci Rep:SiNWs可调节人间充质干细胞的转化

2018-09-09 MedSci MedSci原创

虽然已知来自聚合物基质的生物物理刺激可显著影响人间充质干细胞(hMSCs)的命运,但是纳米尺寸的基于硅的基质对hMSCs的刺激作用尚未完全明了。我们之前已经证明,垂直排列的单晶硅纳米线(SiNW)可以通过SiNWs基质的可控弹簧常数控制hMSCs的成骨性。然而,尚未探究hMSCs在SiNW上的其他可能的分化。 我们假设来自人工SiNWs矩阵的可调弹簧常数可以指导不同类型的hMSCs分化。通过

虽然已知来自聚合物基质的生物物理刺激可显著影响人间充质干细胞(hMSCs)的命运,但是纳米尺寸的基于硅的基质对hMSCs的刺激作用尚未完全明了。我们之前已经证明,垂直排列的单晶硅纳米线(SiNW)可以通过SiNWs基质的可控弹簧常数控制hMSCs的成骨性。然而,尚未探究hMSCs在SiNW上的其他可能的分化。

我们假设来自人工SiNWs矩阵的可调弹簧常数可以指导不同类型的hMSCs分化。通过调整SiNW长度可以一致地控制可调谐SiNW矩阵的弹簧常数。基因表达和细胞硬度的结果表明,hMSCs分化对可区分的SiNWs组弹簧常数敏感,同时具有成骨性和脂肪形成能力。

综上所述,这些发现表明,调整SiNW特性后,SiNW基质可以调节hMSCs的转化。
