Stem cell application for Osteoarthritis in the Knee joint : 

Self-regeneration of the cartilage, which includes chondrocytes, ground substance (cartilage matrix) and elastin fibers, is a slow process which results in new cartilage substance that is not stable for intensive burdens. The fluid inside the joint contains mesenchymal stem cells (MSCs) which can differentiate into chondrocytes, but new deposited cartilage is very fragile and can be destroyed by applying a minimal amount of stress on the joint. Additionally there is only a limited quantity of MSCs in the joint available to differentiate and the process of differentiation is slow.
