Abstract

While current stem cell differentiation protocols generate β cell-enriched islets that reverse hyperglycemia post-implantation, they can cause hypoglycemia. Meng et al.<sup>1</sup> reconstruct endocrine subtype-complete islets, which restore counterregulatory responses and protect against hypoglycemia in diabetic mice, highlighting the importance of endocrine diversity in designing physiologically regulated cell therapies for diabetes.
