近年来,已有研究报道许多植物化学化合物刺激骨生成。在这项研究中,研究人员探究了天然黄酮类白杨素的生物利用度和成骨作用。

通过冷冻干燥方法将白杨素以不同浓度掺入含有羧甲基纤维素,壳聚糖和纳米羟基磷灰石的生物复合材料支架中。探究含有白杨素的支架的物理化学性质和材料特性,而白杨素对它们没有影响。

结果显示,这些含有白杨素的支架对小鼠间充质干细胞(mMSC)没有细胞毒性。从支架释放的白杨素可刺激细胞增殖,并促进成骨细胞分化。机制方面,发现来自支架的白杨增强的成骨细胞分化的原因,或是由于这些细胞中成骨细胞分化转录因子Runx2的辅阻遏物的下调。

因此,该研究将诶过表明,来自支架的白杨素可影响mMSCs的增殖和分化,其在骨组织工程中具有潜在的应用前景。
