ABSTRACT

Objective To explore the effect of combined application of improved microencapsulation and intravenous injection of donor liver cells and spleen cells on pancreatic islet xenografts. Methods New born male pigs and SD rats were selected as donors and recipients respectively, and pig pancreatic islet cells were microencapsulated by static electricity improvement microencapsulation. Islet transplantation was performed after injection of donor liver cells and spleen cells via tail vein. The changes in blood glucose and serum C-peptide, the function-possessed days of islet xenografts and diabetes rats living period were observed. Results In combined application group, the function-possessed days of islet xenografts and diabetes rats living period were significantly prolonged (P
