University of British Columbia scientists, in collaboration with an industry partner, have successfully reversed diabetes in mice using stem cells, paving the way for a breakthrough treatment for a disease that affects nearly one in four Canadians.The research by Timothy Kieffer, a professor in the Department of Cellular and Physiological Sciences, and scientists from the New Jersey-based BetaLogics, a division of Janssen Research & Development, LLC, is the first to show that human stem cell transplants can successfully restore insulin production and reverse diabetes in mice. Crucially, they re-created the “feedback loop” that enables insulin levels to automatically rise or fall based on blood glucose levels. The study is published online June 27 in the journal Diabetes.
