ScienceDaily (Apr. 2, 2009) — A new study finds previously unidentified fibrocartilage-forming progenitor cells in degenerating, diseased human cartilage, but not in cartilage from healthy joints. The research, published in the April 3rd issue of the journal Cell Stem Cell, provides valuable insights into the reparative potential of cartilage and may lead to development of regenerative therapies for arthritis.
Osteoarthritis (OA) is an incurable degenerative disease caused by a progressive deterioration of the cartilage that cushions and protects joints. "OA is the most common musculoskeletal disease in the elderly and is likely to be the fourth-leading cause of disability by the year 2020," explains senior study author Dr. Nicolai Miosge from Georg August University in Goettingen, Germany. "This is our motivation for the further exploration of OA treatment options, including regenerative cell biological therapy."...
