Abstract

Human induced pluripotent stem cells (hiPSC) are considered promising sources of pancreatic islet organoids to treat diabetes. Due to that epigenetic memory predisposes iPSCs to enhanced differentiation into the parental cell type, we sought to generate iPSC lines from islet cells isolated from healthy adult pancreata. Islet cells were reprogrammed with CytoTune-iPS 2.0 Sendai Reprogramming Kit, where the generated iPSCs showed normal karyotype, expression of pluripotency associated markers and in vivoteratoma formation. This cell line will be a valuable resource for drug screening, and potential source for high-efficient generation of insulin-producing islets for treating diabetes.

摘要

人诱导多能干细胞(hiPSC)被认为是有前途的胰岛类器官的来源,可以用于治疗糖尿病。由于表观遗传记忆使 iPS 细胞更容易向亲代细胞类型分化,我们试图从健康成人胰腺中分离的胰岛细胞中生成 iPSC 系。使用 CytoTune-iPS 2.0 Sendai 重编程试剂盒对胰岛细胞进行重编程,生成的 iPS 细胞显示正常核型、多能性相关标志物的表达和体内畸胎瘤形成。该细胞系将成为药物筛选的有价值资源,并且可能成为高效生成用于治疗糖尿病的胰岛素产生胰岛的来源。
