Abstract

Articular cartilage defect treatment is a very important problem because its therapeutic options are not successful enough. Due to the weak self-repairing capacity of the avascular cartilage, even minor damage can progress and cause joint damage leading to osteoarthritis. Although various treatment strategies have been developed to repair damaged cartilage, cell- and exosome-based therapies are promising. Plant extracts have been used for decades, and their effects on cartilage regeneration have been studied. Exosome-like vesicles, which are secreted by all living cells, are involved in cell-to-cell communication and cell homeostasis. The differentiation potential of exosome-like vesicles isolated from S. lycopersicum and C. limon, which are known to have anti-inflammatory and antioxidant properties, was investigated in the differentiation of human adipose-derived mesenchymal stem cells (hASCs) into chondrocytes. In order to obtain tomato-derived exosome-like vesicles (TELVs) and lemon-derived exosome-like vesicles (LELVs) Aquous Two- Phase system was performed. Characterisation of isolated vesicles based on size, shape were achived via Zetasizer, NTA FAME analysis, and SEM techniques. These results showed that TELVs and LELVs increased cell viability and did not show any toxic effects on stem cells. Although TELVs triggered chondrocyte formation, LELVs downregulated. The expression of ACAN, SOX9, and COMP, known as chondrocyte markers, was increased by TELV treatment. In addition, protein expression of the two most important proteins, COL2 and COLXI, found in the extracellular matrix of cartilage, increased. These findings suggest that TELVs can be used for cartilage regeneration, and may be a novel and promising treatment for osteoarthritis.

摘要

关节软骨缺损的治疗是一个非常重要的问题,因为其治疗选择不够成功。由于血管化软骨的自我修复能力较弱,即使是轻微的损伤也会进展并导致关节损伤,进而导致骨关节炎。尽管已经开发了各种治疗策略来修复受损的软骨,但基于细胞和外泌体的治疗方法很有前途。植物提取物已被使用了几十年,其对软骨再生的影响也已被研究。外泌体样小泡是所有活细胞分泌的,参与细胞间通讯和细胞内稳态。从具有抗炎和抗氧化特性的番茄和柠檬中分离出的外泌体样小泡的分化潜能,在人脂肪间充质干细胞(hASC)分化为软骨细胞的过程中进行了研究。为了获得番茄来源的外泌体样小泡(TELVs)和柠檬来源的外泌体样小泡(LELVs),采用了 Aquous Two-Phase 系统。通过 Zetasizer、NTA FAME 分析和 SEM 技术对分离出的小泡的大小、形状进行了表征。这些结果表明,TELVs 和 LELVs 提高了细胞活力,对干细胞没有显示出任何毒性作用。尽管 TELVs 触发了软骨细胞的形成,但 LELVs 却下调了。TELV 处理增加了已知作为软骨细胞标志物的 ACAN、SOX9 和 COMP 的表达。此外,COL2 和 COLXI 这两种在软骨细胞外基质中含量最丰富的两种重要蛋白的表达也增加了。这些发现表明,TELVs 可用于软骨再生,可能是骨关节炎的一种新的有前途的治疗方法。
