The usefulness and limitations of the diabetic macaque model in evaluating long-term porcine islet xenograft survival.

abstract：:Islet transplantation is a potential treatment for diabetes mellitus and porcine pancreata may provide a readily available source of islets. The size, number and distribution of islets within the pancreas may influence the choice of age of donor for xenotransplantation. Samples (n = 3 per age group) from the dorsal an...
