Due to its avascular nature, biomechanical properties of the cartilage tissue in a synovial joint are particularly compromised as the disease progresses. Current therapies for OA merely buy time until arthrodesis or arthroplasty, the ‘end game’, is ultimately reached. Over the last two decades, promising experimental data has started to emerge on mesenchymal stem cells (MSCs) as candidate cell types for cell and/ or tissue-based cartilage tissue repair. The principal attraction of MSCs lies in their consistent chondrogenic differentiation and proliferative propensities. Practically, they offer ease of isolation and culture-expansion. Targeted gene therapy can further enhance their delivery into osteoarthritic joints. Henceforth, understanding the biological activities and mechanisms of action of MSCs is crucial for a rational approach to their clinical application in osteoarthritic joints.Keywords: Mesenchymal stem cells, osteoarthritis, cartilage, cell-based therapy, immuno-modulation
