Paper Talk · Mar 18, 2026 · 19m

Researchers have successfully reconstructed human pluripotent stem cell-derived islets that contain all five essential endocrine cell types. Unlike previous versions that primarily focused on insulin-producing cells, these new islets incorporate a balanced composition of both $eta$ and non-$eta$ cells. When transplanted into diabetic mice, these engineered islets demonstrated the ability to regulate blood glucose levels in both directions, effectively lowering high sugar levels while also preventing dangerous drops. This development is significant because it restores the natural…
