Fibroblast growth factor receptor 1-bound extracellular vesicle as novel therapy for osteoarthritis.

Osteoarthritis (OA) is a joint condition that causes significant impairment of the chondrocyte. The gradual degradation of the cartilage lining of one or more freely moving joints, as well as persistent inflammation, are the causes of osteoarthritis. Current medications focus on alleviating symptoms rather than curing the condition. The aim of this review is to evaluate the potential use of fibroblast growth factor receptor 1-bound extracellular vesicle as novel therapy for osteoarthritis. This review article was completed by searching for the keywords "Fibroblast Growth Factor Receptor 1", "Extracellular Vesicle", and "Osteoarthritis" in various journals in several search engines. Of the 102 scientific articles found, 95 were found suitable to be used as material in the making of this article. The upregulated amount of FGFR1 (fibroblast growth factor receptors) signalling suggesting the progression of degenerative cartilage that commonly seen in osteoarthritis (OA) patients. Several studies showed that the involvement of extracellular vesicles (EV) derived from MSCs could enhance cartilage repair and protect the cartilage from degradation. EVs have the potential to deliver effects to specific cell types through ligand-receptor interactions and several pathway mechanisms related with the FGFR1. EVs and FGFR1-bound Evs have been postulated in recent years as possible therapeutic targets in human articular cartilage. The protective benefits on both chondrocytes and synoviocytes in OA patients can be achieved by administering the MSC-EVs that may also stimulate chondrocyte proliferation and migration EVs have a promising potential to become a novel therapy for treating patients with OA. However, further researches are need to be conducted to discover further the application of this therapy.
