摘要:


文题释义:

骨髓间充质干细胞:是一种多潜能干细胞,具有免疫原性低、安全性好的优点,可以通过促进细胞迁移、归巢修复受损部位来治疗多种神经退行性疾病、中枢神经系统损伤和骨关节软骨退变。
CCR1、CXCR4因子:能够有效诱导干细胞增殖、迁移的趋化因子,使干细胞到达受损部位,实现细胞动员和归巢。


背景:槲皮素在骨髓间充质干细胞增殖和分化中起重要作用,但关于其促进骨髓间充质干细胞迁移的机制研究较少。

目的:通过体外实验研究槲皮素对人骨髓间充质干细胞迁移的影响,并探讨CCR1、CXCR4的调控作用。
方法:选取人骨髓间充质干细胞作为实验对象。CCK-8法检测槲皮素对人骨髓间充质干细胞增殖活性的影响;细胞划痕实验和Transwell实验分别检测槲皮素处理后人骨髓间充质干细胞的体外侵袭和迁移能力;借助分子对接技术进一步展示槲皮素与CCR1、CXCR4之间的作用关系;Western blot和实时荧光定量PCR检测槲皮素处理后迁移相关趋化因子的表达。

结果与结论:①5,10 μmol/L槲皮素具有显著促进人骨髓间充质干细胞增殖的作用,且药物浓度在10 μmol/L时,细胞增殖效率最高;②为更好地探索槲皮素影响人骨髓间充质干细胞迁移的量效关系,选取 5,10 μmol/L槲皮素进行后续实验,采用川芎嗪作为阳性对照药物,实验分为空白对照组、5 μmol/L槲皮素组、10 μmol/L槲皮素组和100 μmol/L川芎嗪组;③槲皮素处理后人骨髓间充质干细胞的体外迁移和侵袭能力呈浓度依赖性提升,10 μmol/L槲皮素组的迁移效果优于川芎嗪组;④分子对接结果提示槲皮素与CCR1、CXCR4之间存在强烈的相互作用;⑤槲皮素可以上调CCR1、CXCR4蛋白和mRNA的表达;⑥该研究在细胞水平上证实了槲皮素可以通过靶向CCR1、CXCR4促进人骨髓间充质干细胞的迁移。

Abstract: BACKGROUND: Quercetin plays an important role in the proliferation and differentiation of bone marrow mesenchymal stem cells, but less research has been done on its mechanism of promoting the migration of bone marrow mesenchymal stem cells. 
OBJECTIVE: To study the effect of quercetin on the migration of human bone marrow mesenchymal stem cells through in vitro experiments, and to explore the regulatory role of CCR1 and CXCR4.
METHODS: Human bone marrow mesenchymal stem cells were selected as experimental subjects. CCK8 assay was used to detect the effect of quercetin on the proliferative activity of human bone marrow mesenchymal stem cells. Cell scratch assay and Transwell assay were used to detect the in vitro invasive and migratory abilities of human bone marrow mesenchymal stem cells after quercetin treatment, respectively. The role of quercetin in relation to CCR1 and CXCR4 was demonstrated with the help of molecular docking technology. Western blot assay and real-time fluorescence quantitative PCR were used to detect the migration-related chemokine expression after quercetin treatment. 
RESULTS AND CONCLUSION: (1) 5 and 10 μmol/L quercetin could significantly promote the proliferation of human bone marrow mesenchymal stem cells, and the drug concentration of 10 μmol/L resulted in the highest cell proliferation efficiency. (2) To better explore the dose-effect relationship of quercetin affecting the migration of human bone marrow mesenchymal stem cells, 5 and 10 μmol/L quercetin were selected for the subsequent experiments, and ligustrazine was used as the positive control drug, and the experiments were divided into blank control group, 5 μmol/L quercetin group, 10 μmol/L quercetin group, and 100 μmol/L ligustrazine group. (3) In vitro migration and invasion ability of human bone marrow mesenchymal stem cells were elevated in a concentration-dependent manner after quercetin treatment, and the migration effect of 10 μmol/L quercetin group was better than that of ligustrazine group. (4) The molecular docking results suggested that there was a strong interaction between quercetin and CCR1 and CXCR4. (5) Quercetin could up-regulate the expression of CCR1 and CXCR4 proteins and mRNA. (6) This study confirmed at the cellular level that quercetin could promote the migration of human bone marrow mesenchymal stem cells by targeting CCR1 and CXCR4.
