Seaweed-Encapsulated Cells for Treating Diabetes.Type 1 diabetes results from a civil war within the body: the immune system, for reasons not well understood, attacks and destroys blood-sugar-regulating β cells. Patients must carefully control their own blood sugar with frequent pinpricks and insulin injections. But what if doctors could simply replace the destroyed cells?
Image: In this image, researchers have placed β cells (green) inside of a ball of alginate, a seaweed-based polymer, and have implanted the ball into a model organism. This alginate capsule could protect β cells from immune attacks while still allowing them to sense and regulate blood sugar.
