项目摘要
After thawing the cryopreserved islets with UW solution, the islet cells showed an efficient monolayer formation and facilitated effective lentivirus-mediated transduction. Monolayer formation of mouse islets was efficiently achieved by the use of extracellular matrices derived from 804G cells. We successfully made a diabetes model in pigs to perform total pancreatectomy. Such diabetic pigs died of ketoacidosis within 10 days after surgery. The model would be useful to assess the efficacy of diabetes-targeted cell therapies. A human pancreatic beta cell line that is functionally equivalent to primary beta cells has not been available. We established a reversibly immortalized human beta cell clone (NAKT-15) by transfection of primary human beta cells with a retroviral vector containing simian virus 40 large T antigen (SV40T) and human telomerase reverse transcriptase (hTERT) cDNAs flanked by paired recombination target loxPs, which allows deletion of SV40T and hTERT genes by Cre recombinase. Reverted NAKT-15 cells expressed beta cell transcription factors (Isl-1,Pax 6,Nkx 6.1,Pdx-1), prohormone convertases 1/3 and 2, and secretory granule proteins, and secreted insulin in response to glucose, similar to normal human islets. Transplantation of NAKT-15 cells into streptozotocin-induced diabetic SCID mice resulted in perfect control of blood glucose within 2 weeks ; mice remained normoglycemic for longer than 30 weeks. The establishment of a beta cell line is one step toward the potential cure of diabetes by transplantation.
用 UW 溶液解冻冷冻保存的胰岛后,胰岛细胞显示出有效的单层形成,并促进有效的慢病毒介导的转导。通过使用源自 804G 细胞的细胞外基质,有效地实现了小鼠胰岛的单层形成。我们成功地在猪身上建立了糖尿病模型来进行全胰腺切除术。这样的糖尿病猪在手术后10天内就死于酮症酸中毒。该模型将有助于评估糖尿病靶向细胞疗法的功效。目前还没有与原代 β 细胞功能相同的人类胰腺 β 细胞系。我们通过用含有猿病毒 40 大 T 抗原 (SV40T) 和人端粒酶逆转录酶 (hTERT) cDNA 的逆转录病毒载体转染原代人 β 细胞,建立了可逆永生化人 β 细胞克隆 (NAKT-15),该载体两侧是配对重组靶标 loxPs,允许通过 Cre 删除 SV40T 和 hTERT 基因。 重组酶。恢复的 NAKT-15 细胞表达 β 细胞转录因子(Isl-1、Pax 6、Nkx 6.1、Pdx-1)、激素原转化酶 1/3 和 2 以及分泌颗粒蛋白,并响应葡萄糖分泌胰岛素,与正常人胰岛相似。将NAKT-15细胞移植到链脲佐菌素诱导的糖尿病SCID小鼠体内,两周内血糖得到完美控制;小鼠血糖保持正常状态超过 30 周。 β细胞系的建立是通过移植治愈糖尿病的一步。
