Responders vs. Non-Responders to Mesenchymal Stromal Cells in Knee Osteoarthritis: Mechanistic Correlates of Donor Cell and Patient Features
Mesenchymal stromal cell (MSC) injection has afforded heterogeneous outcomes in knee osteoarthritis (KOA). Herein, a framework that dually correlates KOA patient responsiveness with baseline autologous bone marrow-derived MSC(M) donor batch attributes and baseline clinical and biomarker features is provided. Using clinical trial data (NCT02351011), we demonstrated that MSC(M) with increased immunomodulatory potency are more efficacious. Multivariable MSC(M) genes correlated strongly with responder status and 12- and 24-month improvements in Knee Injury and Osteoarthritis Outcome Scores.
