Another success for adult stem cells, again treating Type I (juvenile) diabetes patients. As reported in a study published today in the Journal of the American Medical Association, 20 of 23 patients became insulin-independent after treatment with their own bone marrow adult stem cells. This report is a follow-up to the previous report by Voltarelli & Burt in 2007, and includes new patients as well as a longer period to follow the patients. Some of the patients have gone for four years insulin-free. The authors note in the paper that this adult stem cell treatment "remains the only treatment capable of reversing type 1 diabetes in humans."
