Encapsulated beta cells give hope to diabetics

Scientists learned how to grow "blanks" of beta cells that produce insulin molecules, and pack them into special shells that allowed them to reach the pancreas. Injection of such cells dramatically improved the condition of mice suffering from type 2 diabetes.
