Synovial Mesenchymal Stem Cell-Derived Exosomal miR-485-3p Relieves Cartilage Damage in Osteoarthritis by Targeting the NRP1-Mediated PI3K/Akt Pathway

Cartilage cell functions were detected by CCK-8, scratch assay, and flow cytometry, respectively. Inflammatory cytokine levels were assessed by ELISA. Target molecule levels were measured by qRT‒PCR and Western blotting.
