Summary:
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 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 today in the journal Diabetes.
After the stem cell transplant, the diabetic mice were weaned off insulin, a procedure designed to mimic human clinical conditions. Three to four months later, the mice were able to maintain healthy blood sugar levels even when being fed large quantities of sugar. Transplanted cells removed from the mice after several months had all the markings of normal insulin-producing pancreatic cells.
