Diagram of pig islet cells encapsulated within a seaweed-based alginate coating. Living Cell Technologies (LCT) encapsulates the islet cells to protect them from the transplant recipient’s immune system. The coating is semi-permeable – it allows small molecules, such as nutrients and insulin, to diffuse in and out but is a physical barrier to larger molecules, such as antibodies.
