摘要:

文题释义:

骨髓间充质干细胞:是一种多能成体干细胞,主要存在于骨髓基质中,这些细胞具有自我更新和多向分化的特性,能分化为骨、软骨、脂肪等组织细胞。骨髓间充质干细胞具有免疫调节功能,可分泌多种生长因子,在组织修复、再生医学和细胞治疗领域具有重要研究价值。
蛇床子素:是一种从蛇床子植物中提取的生物活性化合物,属于倍半萜内酯类成分。蛇床子素具有抗炎、抗氧化、抗肿瘤等多种药理学特性。

摘要
背景:糖尿病患者的高血糖状态会损害骨髓间充质干细胞的功能,导致骨愈合障碍等并发症。蛇床子素作为一种天然香豆素类化合物,具有促进成骨分化的潜在作用。
目的:探讨蛇床子素对高糖环境下骨髓间充质干细胞成骨分化功能的影响。
方法:采用CCK-8方法确定高糖环境影响骨髓间充质干细胞的最适浓度及作用时间,以及蛇床子素的最佳作用浓度和时间;将骨髓间充质干细胞分为4组:空白组仅添加基础培养基培养,对照组添加成骨诱导培养基培养,高糖组在成骨诱导培养基的基础上添加25 mmol/L葡萄糖,蛇床子素组在高糖组的基础上添加80 μg/mL蛇床子素。采用碱性磷酸酶活性检测和茜素红染色定量分析评估骨髓间充质干细胞的成骨分化表型;实时荧光定量PCR和免疫荧光技术检测成骨相关因子的表达变化。

结果与结论:①CCK-8实验确定使用25 mmol/L高糖培养基培养3 d构建体外高糖环境模型,蛇床子素的最佳作用质量浓度为80 μg/mL,最佳作用时间为3 d;②在高糖环境下,蛇床子素显著增强了骨髓间充质干细胞的碱性磷酸酶活性和矿化结节形成能力;③与高糖组相比,蛇床子素组Runx2、碱性磷酸酶、Ⅰ型胶原和骨钙素基因表达显著增加(P < 0.05,P < 0.01,P < 0.001);④与高糖组相比,蛇床子素组Runx2和骨钙素蛋白表达显著增加(P < 0.000 1)。结果表明,蛇床子素在高糖环境中可改善骨髓间充质干细胞的成骨分化功能。

Abstract: BACKGROUND: High-glucose conditions in diabetic patients impair the function of bone marrow mesenchymal stem cells, leading to complications such as impaired bone healing. Osthole, a natural coumarin compound, has potential effects on promoting osteogenic differentiation.
OBJECTIVE: To investigate the effects of osthole on the osteogenic differentiation function of bone marrow mesenchymal stem cells under high-glucose conditions. 
METHODS: CCK-8 assay was used to determine the optimal high-glucose concentration and exposure time for bone marrow mesenchymal stem cells, as well as the best osthole concentration and action time. Bone marrow mesenchymal stem cells were divided into four groups: the blank group was cultured with basal medium only; the control group was cultured with osteogenic induction medium; the high glucose group was cultured with 25 mmol/L glucose on the basis of osteogenic induction medium; the osthole group was cultured with 80 μg/mL osthole on the basis of the high glucose group. Alkaline phosphatase activity detection and Alizarin Red staining were used to evaluate the osteogenic phenotype of bone marrow mesenchymal stem cells. Real-time fluorescent quantitative PCR and immunofluorescence techniques were employed to detect changes in osteogenic-related factor expression. 
RESULTS AND CONCLUSION: (1) CCK-8 assay confirmed using 25 mmol/L high-glucose medium for 3 days to construct an in vitro high-glucose environment model, with 80 μg/mL as the optimal osthole concentration and 3 days as the optimal action time. (2) Under high-glucose conditions, osthole significantly enhanced alkaline phosphatase activity and mineralization nodule formation ability. (3) Compared with the high-glucose group, the osthole group showed significantly increased expression of Runx2, alkaline phosphatase, type I collagen, and osteocalcin genes (P < 0.05, P < 0.01, P < 0.001). (4) Compared with the high-glucose group, the osthole group showed significantly increased Runx2 and osteocalcin protein expression (P < 0.000 1). The results indicate that osthole can improve the osteogenic differentiation function of bone marrow mesenchymal stem cells in high-glucose environments.
