Induction of insulin-dependent diabetes mellitus by total pancreatectomy for pancreatic islet transplantation in cynomolgus monkeys

摘要

In order to perform a preclinical trial of pancreatic islet transplantation (PIT) in nonhuman primates, insulin-dependent diabetes mellitus (IDDM) must be induced. Methods for IDDM induction are administration of streptozotocin (STZ) or total pancreatectomy (TP). While STZ-induced IDDM is not always reliable, TP is appropriate for IDDM induction. However, TP is very difficult because of the complex surgical procedure required, necessary confirmation of IDDM, and difficulty in postoperative management. In this study, we tried to establish a reliable IDDM model for PIT in cynomolgus monkeys.
