Arthritis is caused by inflammation in your joints. It causes pain and stiffness in affected joints, which usually worsens with age. There are two common forms of arthritis osteoarthritis and rheumatoid arthritis.
Osteoarthritis is the most common form of arthritis that occurs when cartilage, the connective tissue found between bones, breaks down. Rheumatoid arthritis on the other hand is an autoimmune disease, when the immune system attacks and destroys healthy tissue. In people with rheumatoid arthritis, the immune system attacks and breaks down the smooth lining in a joint (called the synovium) causing pain and inflammation.
Due to their regenerative capabilities stem cells are being explored for treating arthritis. The hope is stem cells can regenerate the tissues that are affected by arthritis.
