Abstract
Murine renal subcapsular islet transplantation presents a promising technique for diabetes treatment by addressing challenges such as immune rejection and reliance on immunosuppressive drugs. Here, we present a protocol for the isolation, purification, and transplantation of mouse pancreatic islets that overcomes these challenges. Specifically, we describe steps for inducing diabetes with streptozotocin, pancreatic perfusion and isolation, and islet cell purification. We then detail procedures for renal subcapsular islet transplantation, dual antibody therapy, and immune cell and graft monitoring. For complete details on the use and execution of this protocol, please refer to Liu et al.1.
