Extended Data Fig. 8: Morphological and immunohistochemical analysis of autologous cynomolgus monkey islets, implanted in the subcutaneous space, was performed at the time of euthanasia (animal ID# 212077, POD 918).

We found abundant healthy islet cell clusters, exhibiting vivid expression of key markers such as Insulin, Glucagon, Bcl-2, GLP-1, Ki67, VEGF, VWF and Collagen. Due to IACUC regulations and ethical care guidelines for nonhuman primate research, subcutaneous autologous islet transplants without IVM as a control could not be performed in a cynomolgus monkey.
