Scientists 3D-print functional human islets, fight diabetes

Scientists have successfully 3D-printed functional human islets, potentially paving the way to eliminate insulin injections for diabetes patients. This breakthrough uses a novel bio-ink and 3D printing to create insulin-producing cells. The team, led by Dr. Quentin Perrier, developed a method to print islets that survived and functioned well for up to three weeks. The bioprinted islets responded better to glucose, releasing more insulin when needed, and showed improved sensing of blood sugar levels. The research, using real human islets, is being tested in animal models. The team is also exploring long-term storage and alternative cell sources to address donor shortages, with the goal of creating an off-the-shelf treatment.
