2018 CVM News: Removable implant may control type 1 diabetes

Abstract

This news item from the Cornell Chronicle is about: For the more than 1 million Americans who live with type 1 diabetes, daily insulin injections are literally a matter of life and death. And while there is no cure, a Cornell-led research team has developed a device that could revolutionize management of the disease. In Type 1 diabetes, insulin-producing pancreatic cell clusters (islets) are destroyed by the body’s immune system. The research group, led by assistant professor Minglin Ma from the Department of Biological and Environmental Engineering in the College of Agriculture and Life Sciences, has devised an ingenious method for implanting hundreds of thousands of islet cells into a patient. They are protected by a thin hydrogel coating and, more importantly, the coated cells are attached to a polymer thread and can be removed or replaced easily when they have outlived their usefulness.
