摘要:

人参皂苷Rg3脂质体:此次研究中的人参皂苷Rg3脂质体系通过薄膜分散法制备,以磷脂和胆固醇为主要材料,负载人参皂苷Rg3。人参皂苷Rg3作为中药活性成分具有抗炎与促分化作用,但水溶性差、易降解限制了它的直接应用。脂质体包载方式有效提高了人参皂苷Rg3的稳定性与生物利用度,并且在水凝胶中呈现持续释放特性,为间充质干细胞的定向诱导提供稳定微环境,是此次研究复合水凝胶发挥成软骨功能的关键构件之一。
成软骨分化:是指骨髓间充质干细胞在特定诱导条件下向软骨样细胞表型转化的生物学过程。此次研究通过添加成软骨诱导培养基对骨髓间充质干细胞进行7 d的诱导培养,通过qPCR检测软骨标志基因的表达量化分化效果,通过细胞染色观察细胞外软骨基质合成情况。

背景:人参皂苷Rg3具有潜在的软骨保护及修复价值,但它的应用存在水溶性差、半衰期短、生物利用度低等缺点。为改善药物的药代动力学特性,将药物负载脂质体嵌入甲基化明胶、多糖类或丝素蛋白基水凝胶中已成为软骨组织工程研究的热点。
目的:制备载人参皂苷Rg3脂质体甲基丙烯酰化丝素蛋白水凝胶,进一步分析该水凝胶对小鼠骨髓间充质干细胞成软骨分化的作用。
方法:①采用薄膜分散法制备人参皂苷Rg3脂质体,将Dil标记的脂质体与小鼠骨髓间充质干细胞共培养,鬼笔环肽染色检测细胞摄取脂质体情况。制备甲基丙烯酰化丝素蛋白(记为SilMA),将人参皂苷Rg3脂质体与SilMA混合,通过光交联制备复合水凝胶(记为SilMA@Lipo-Rg3),评估该水凝胶的微观形貌、力学性能、流变性能、溶胀性能与药物缓释性能。②采用不同浓度的SilMA水凝胶浸提液或SilMA@Lipo-Rg3水凝胶浸提液培养小鼠骨髓间充质干细胞,通过CCK-8检测与活死细胞染色评估材料的细胞相容性。分别采用1/8浓度的SilMA水凝胶浸提液、SilMA@Lipo-Rg3水凝胶浸提液培养小鼠骨髓间充质干细胞,成软骨诱导后,qPCR检测Ⅱ型胶原蛋白、SOX9、聚集蛋白聚糖mRNA表达,阿尔新蓝和番红O染色检测细胞内蛋白多糖、糖胺聚糖表达。
结果与结论:①鬼笔环肽染色显示,Dil标记的脂质体能够被小鼠骨髓间充质干细胞成功摄取。扫描电镜显示SilMA@Lipo-Rg3水凝胶呈现疏松多孔的网格结构。压缩实验与流变性能测试显示,与SilMA水凝胶相比,SilMA@Lipo-Rg3水凝胶的压缩刚度略有下降;两种水凝胶的溶胀性能无明显差异。SilMA@Lipo-Rg3水凝胶具有良好的缓释性能,可持续释放人参皂苷Rg3 14 d以上。②CCK-8检测与活死细胞染色显示,SilMA、SilMA@Lipo-Rg3水凝胶具有良好的细胞相容性。qPCR检测显示,SilMA@Lipo-Rg3组细胞内Ⅱ型胶原蛋白、SOX9、聚集蛋白聚糖mRNA表达高于SilMA组(P < 0.05);阿尔新蓝和番红O染色显示,SilMA@Lipo-Rg3组细胞内蛋白多糖、糖胺聚糖表达多于SilMA组。结果表明,SilMA@Lipo-Rg3水凝胶可促进小鼠骨髓间充质干细胞的成软骨分化。

Abstract: BACKGROUND: Ginsenoside Rg3 has potential for cartilage protection and repair, but its application suffers from drawbacks such as poor water solubility, short half-life, and low bioavailability. To improve drug pharmacokinetic properties, embedding drug-loaded liposomes into methylated gelatin, polysaccharide, or silk fibroin-based hydrogels has become a hot topic in cartilage tissue engineering research.
OBJECTIVE: To fabricate liposome-methacryloylated silk fibroin hydrogels loaded with ginsenoside Rg3 and further analyze the effects of these hydrogels on the chondrogenic differentiation of mouse bone marrow mesenchymal stem cells.
METHODS: (1) Ginsenoside Rg3 liposomes were prepared by a thin film dispersion method. Dil-labeled liposomes were co-cultured with mouse bone marrow mesenchymal stem cells, and cellular uptake of the liposomes was assessed by phalloidin staining. Methacryloylated silk fibroin (SilMA) was prepared. Ginsenoside Rg3 liposomes were mixed with SilMA and photocrosslinked to form a composite hydrogel (SilMA@Lipo-Rg3). The micromorphology, mechanical properties, rheological properties, swelling properties, and drug release performance of the hydrogel were evaluated. (2) Mouse bone marrow mesenchymal stem cells were cultured with different concentrations of SilMA hydrogel extract or SilMA@Lipo-Rg3 hydrogel extract. The cytocompatibility of the materials was evaluated by CCK-8 assay and live-dead cell staining. Mouse bone marrow mesenchymal stem cells were cultured with 1/8 concentration of SilMA hydrogel extract or SilMA@Lipo-Rg3 hydrogel extract, respectively. After chondrogenic induction, the expression of type II collagen, SOX9, and aggrecan mRNA was measured by qPCR. The expression of intracellular proteoglycans and glycosaminoglycans was detected by Alcian blue and safranin O staining.
RESULTS AND CONCLUSION: (1) Phalloidin staining revealed that Dil-labeled liposomes were successfully taken up by mouse bone marrow mesenchymal stem cells. Scanning electron microscopy revealed that the SilMA@Lipo-Rg3 hydrogel exhibited a loose and porous lattice structure. Compression tests and rheological tests revealed that the compressive stiffness of the SilMA@Lipo-Rg3 hydrogel was slightly lower than that of the SilMA hydrogel; there was no significant difference in the swelling properties of the two hydrogels. The SilMA@Lipo-Rg3 hydrogel exhibited excellent sustained-release properties, releasing ginsenoside Rg3 for more than 14 days. (2) CCK-8 assay and live-dead cell staining revealed that the SilMA and SilMA@Lipo-Rg3 hydrogels exhibited good cytocompatibility. qPCR analysis showed that the mRNA expression of type II collagen, SOX9, and aggrecan in the SilMA@Lipo-Rg3 group was higher than that in the SilMA group (P < 0.05). Alcian blue and safranin O staining revealed that the expression of proteoglycans and glycosaminoglycans in the SilMA@Lipo-Rg3 group was higher than that in the SilMA group. These results indicate that the SilMA@Lipo-Rg3 hydrogel promotes the chondrogenic differentiation of mouse bone marrow mesenchymal stem cells.
