Matrix-Bound Growth Factors Are Released Upon Cartilage Compression by an Aggrecan-Dependent Sodium Flux That is Lost in Osteoarthritis

Abstract

Significance Statement: Osteoarthritis is the most prevalent musculoskeletal disease, affecting 250 million people worldwide. We identify a novel intrinsic repair response in cartilage, mediated by aggrecan-dependent sodium flux, and dependent upon matrix stiffness, which results in the release of a cocktail of pro-regenerative growth factors after injury. Loss of aggrecan in late-stage osteoarthritis prevents growth factor release and likely contributes to disease progression. Treatments that restore matrix sodium in osteoarthritis may recover the intrinsic repair response to improve disease outcome.
