An anonymous reader writes "Scientists successfully reversed diabetes in mice by transplanting mice human stem cells into mice in a discovery that may lead to way to finding a cure for a disease that affects 8.3 percent of the U.S. population. ... In an experiment designed to mimic human clinical conditions, researchers were able to wean diabetic mice off of insulin four months after the rodents were transplanted with human pancreatic stem cells (abstract). [They] were able to recreate the 'feedback loop' that enabled insulin levels to automatically rise or fall based on the rodents' blood glucose levels. Additionally, researchers found that the mice were able to maintain healthy blood sugar levels even after they were fed large quantities of sugar. After several months, researchers removed the transplanted cells from the mice and found that the cells had all the markings of normal insulin-producing pancreatic cells."
