Abstract: Objective: To study the effect of echinacoside on the osteogenic differentiation of rat adipose derived stem cells (ADSCs) and its further underlying mechanism. Methods: ADSCs were subjected to 0.01,0.1 and 1 mg/mL echinacoside culture solution,the control group was ADSCs cultured without echinacoside. The proliferation of ADSCs was tested with MTT assay, the osteogenic differentiation was investigated using alkaline phosphatase (ALP) staining, semi-quantitation of ALP, alizarin red S (ARS) staining, and semi-quantitation of ARS. The expression of phosphorylated extracellular signal-regulated kinase (ERK), p38 kinase and c-Jun N terminal kinase (JNK) was analyzed with Western blot. Results: Results showed that the proliferation of ADSCs was not impacted by echinacoside (P>0.05). ALP staining and ARS staining were stronger in 0.01, 0.1 and 1 mg/mL echinacoside culture solution groups. ALP and ARS activity quantitative assay demonstrated significantly higher in echinacoside groups(P<0.05). Western blot results demonstrated that echinacoside rapidly phosphorylated ERK, p38 and JNK. Conclusion: Echinacoside could promote the osteogenic differentiation of ADSCs, while not impact its proliferation, a potential mechanism involving ERK, p38 and JNK MAPK pathways.

摘要: 目的:探讨松果菊苷对大鼠脂肪来源干细胞(ADSCs)成骨分化的作用及其可能机制。方法:以0.01、0.1和1 mg/mL松果菊苷培养液培养ADSCs,未加松果菊苷的培养液作为对照组,应用 MTT 法检测松果菊苷对细胞增殖活性的影响,碱性磷酸酶(ALP)染色和半定量检测细胞 ALP 的表达,茜素红染色(ARS)和半定量检测细胞的基质矿化,Western blot 检测ERK、p38 和 JNK 的蛋白磷酸化水平。结果:1、4、7 d,0.01及0.1和1 mg/mL松果菊苷培养液对大鼠ADSCs的增殖活性无显著影响(P>0.05); 0.01、0.1和1 mg/mL松果菊苷培养液组ALP染色和ARS染色较对照组深染,ALP蛋白分泌和ARS基质矿化均较对照组有显著的增加(P<0.05);0.01 mg/mL松果菊苷培养液作用下ERK、p38和JNK的蛋白磷酸化水平升高。结论:松果菊苷对ADSCs增殖无影响,可促进ADSCs向成骨方向分化,其作用机制与MAPK 信号通路有关。
