Cellular encapsulation holds promise for immunosuppression-free pancreatic islet transplantation. However, long-term graft survival remains a challenge, especially at the subcutaneous site. We harnessed temporary, controlled, inflammation-induced neovascularization to create a modified subcutaneous cavity that supports long-term survival and function of a customized islet encapsulation device without immunosuppression.
