Scheme of the experiment. Mesenchymal stem cells (MSCs) were isolated from the synovium of the knee of a human patient with osteoarthritis. A cylindrical piece of cartilage was removed from the femur of a pig and its surface was abraded. The MSC suspension was placed on the cartilage surface, washed after a specified time, and the number and morphology of MSCs adhered to the surface of the cartilage were evaluated.
