Özet

Background: Cartilage injuries are currently the most prevalent joint disease. Previous studies have emphasized the use of stem cells as the effective treatment for regenerating cartilage damage.

Objective: In this study, considering the difficulties of the cellular therapy method, it was hypothesized that human synovial fluid-derived mesenchymal stem cell (hSFMSC) exosomes as a SC source could be used to treat these injuries as a safer and cell-free therapeutic alternative procedure due to its direct relevance to cartilage regeneration. Moreover, this study aimed to determine the miRNA and target genes required for the formation of SC treatment combined with gene therapy in order to reveal the mechanism of cartilage regeneration and increase its effectiveness.

Methods: MSCs were characterized by flow cytometry, and immunocytochemical and differentiation analyses were done. To characterize functionally isolated exosomes, in vitro uptake analysis was performed. RT-qPCR was used to examine in terms of the advantages of cellular and cell-free therapy, mature human chondroblasts derived by differentiation from hSF-MSCs and human chondrocyte profiles were compared in order to demonstrate the above profile of hSF-MSCs and exosomes isolated from them, and the effectiveness of SC therapy in repairing cartilage damage.

Results: According to our findings, the expression level of hsa-miR-155-5p was found to be considerably higher in chondrocytes differentiated from human synovial fluid MSCs than in mature human chondrocytes. These findings were also supported by the TGF-signalling pathway and chondrogenesis marker genes.

Conclusion: It was concluded that hSF-MSCs and exosomes can be used in the treatment of cartilage damage, and hsa-miR-155-5p can be used as a target miRNA in a new gene therapy approach because it increases the therapeutic effect on cartilage damage.
