This is potential good news for people with arthritis. In animal studies, muscle stem cells have been converted into cartilage and used to treat arthritis. As the person who sent this item to me put it only slightly tongue in cheek: “Perhaps the NYT should be notified. But then, they would ‘neutrally’ report a ‘stem cell success’, followed by a Bush-bashing statement about how ‘stem cell research’ is not being funded.” Too true. Too true.
