Tiny implant cures diabetes in mice without triggering immune response

Researchers at Washington University School of Medicine in St. Louis and Cornell University have collaborated to implant insulin-secreting beta cells grown from human stem cells into mice with diabetes, to normalize their blood sugar. The cells pictured (in purple) are inside a tiny implant that is porous enough to allow these cells to secrete insulin — yet small enough to prevent immune cells from accessing and destroying them.
