ScienceDaily (Feb. 24, 2009) — A strain of laboratory mice that has “superhealing” powers has been found to resist inflammation after a knee injury, and also to avoid developing arthritis at the injury site in the long term, according to researchers at Duke University Medical Center. Their findings illuminate the mechanisms of post-traumatic arthritis and could point to therapies for this condition, which commonly afflicts younger people who lose productivity during their prime working years.
