摘要: 目的 研究射干苷(tectoridin)、桃叶珊瑚苷(aucubin)对脂多糖(LPS)诱导后人脂肪间充质干细胞(hAMSCs)免疫调控作用的影响。方法 通过CCK-8细胞增殖实验和细胞周期检测实验,筛选合适药物作用浓度;筛选LPS作用浓度,建立炎性反应模型;用ELISA、RT-qPCR检测两者对LPS诱导后hAMSCs分泌促炎因子、抑炎因子的影响。结果 50μg/mL射干苷和100μg/mL桃叶珊瑚苷能明显促进hAMSCs增殖(P<0.05,P<0.01);两者均促进LPS诱导后hAMSCs增殖(P<0.001),并且,可抑制hAMSCs分泌IL-6、TNF-α、IFN-γ等促炎因子(P<0.05,P<0.01)。结论 射干苷、桃叶珊瑚苷可显著抑制LPS诱导的hAMSCs炎性反应。

Abstract: Objective To study the effects of tectoridin and aucubin on the immune regulation of human adipose mesenchymal stem cells (hAMSCs) induced by lipopolysaccharide (LPS).Methods CCK-8 cell proliferation test and cell cycle test were used to screen the appropriate concentration of drugs; LPS concentration was screened to establish an inflammatory response model; ELISA and RT-q PCR were used to detect the effects of both on the secretion of pro-inflammatory and anti-inflammatory factors by hAMSCs after LPS induction. Results 50μg/mL tectoridin and 100μg/mL aucubin could significantly promote the proliferation of normal hAMSCs (P < 0.05 ,P<0.01). Both of them promoted the proliferation of hAMSCs induced by LPS (P<0.001), and inhibited the secretion of IL-6,TNF-α,IFN-γ (P<0.05 ,P<0.01) .Conclusions Tectoridin and aucubin could significantly inhibit LPS-induced hAMSCs inflammatory response.
