  • Report of 3 cases of transplantation of GGTA1 gene knockout porcine islet cells into type Ⅰ diabetic macaques

    ObjectiveTo explore the effect of transplanting neonatal porcine islet cells of pig via hepatic portal vein in type Ⅰ diabetic monkeys.MethodIn this study, three pig-monkey islet xenotransplantation experiments were carried out by using α-1, 3-galactosyltransferase (GGTA1) gene knockout neonatal pig islet cells.ResultsThree macaques were successfully transplanted with islet cells. After the operation, their vital signs were stable and no symptoms of venous embolism occurred. After transplantation, the blood glucose and the dosage of exogenous insulin were significantly reduced, and the specific porcine C-peptide could be detected. Three macaques developed symptoms of ketoacidosis, and one macaque developed wound infection. After symptomatic treatment, all of them survived for 16 weeks.ConclusionGGTA1 knockout neonatal porcine islet cells transplanted through hepatic portal vein is effective for the treatment of type Ⅰ diabetes.
