Human pluripotent stem cell-derived pancreatic islets (PSC-islets) hold promise in type I diabetes treatment, although their delivery is a challenge. We describe a new abdominal infusion transplantation protocol that enables the survival, maturation and maintenance of functional PSC-islets in diabetic monkeys.
