摘要:
目的:细胞外囊泡(EVs)可修饰性强,可携带多种生物活性因子,无免疫原性,分析其在干细胞膜载体研究中的潜力。方法:通过超声法制备一种载淫羊藿苷胞外囊泡纳米复合物,旨在检测其是否能有效地诱导骨髓间充质干细胞(BMSCs)的成骨分化。选取载药量最高的ICA-EVs复合物,以游离ICA为对照,检测其对BMSCs细胞矿化及成骨分化相关基因ALP,β-catenin,Runx2表达的影响。结果:ICA-EVs在14 d时矿化作用显著,碱性磷酸酶活性增加,差异有统计学意义(P<0.01),β-catenin,Runx2蛋白表达增高,差异有统计学意义(P<0.05)。结论:ICA-EVs能够促进BMSCs的矿化和成骨分化,有望取代直接干细胞移植用于骨缺损修复和再生。
Abstract:
To explore the effect of icariin extracellular vesicles(ICA-EVs)for marrow mesenchymal stem cells(BMSCs).Methods:Icariin loaded extracellular vesicle nanocomposites were prepared by ultrasonic method to detect whether it can effectively induce the osteogenic differentiation of BMSCs.The effects of ICA-EVs complex with the highest drug loading on the expression of ALP,β-catenin and Runx2 in BMSCs were detected with free ICA as control.Results:The mineralization of ICA-EVs was significant at 14 d,and alkaline phosphatase activity increased(P<0.01),the expression of β-catenin and Runx2 protein were also increased(P<0.05).Conclusion:ICA-EVs can promote the mineralization and osteogenic differentiation of BMSCs,which is expected to replace direct stem cell transplantation for bone defect repair and regeneration.
