Abstract

An innovative microneedle (MN)-based cell therapy is developed for glucose-responsive regulation of the insulin secretion from exogenous pancreatic β-cells without implantation. One MN patch can quickly reduce the blood-sugar levels (BGLs) of chemically induced type-1 diabetic mice and stabilize BGLs at a reduced level for over 10 h.
