| Outline of Final Research Achievements |
We reported islets can be short-term cultured for 14 days using serum-free medium containing sericin instead of FBS.The study evaluated the use of the medium containing sericin and albumin for islet long-term culture. Twenty rat islets were cultured in medium containing ①FBS,②sericin,③bovine serum albumin(BSA),④sericin+BSA,⑤FBS+sericin. The cultured islets in ②and③ were disappered for either 35 and 77days. The survival rates for 120 days of ①,④and⑤ were either 24,24,and 13%. Insulin secretions of the ①and④ were measured by static incubation on the day120, and no significant differences in stimulated insulin secretion were noted between the groups. In vivo function of cultured islets of ①and④ were tested by syngeneic transplantation for diabetes rats, and both recipients were maintained normal glycemic control for 28 days after transplantation. Histologically, islets after transplantation with ④ was displayed well-preserved structure and strong insulin staining.
