Peripheral blood mononuclear cells (PBMCs) were collected from a clinically diagnosed 64-year old male Parkinson's disease (PD) patient with N551K variant in the LRRK2 gene. The PMBCs were reprogrammed with the human OSKM transcription factors using the Sendai-virus reprogramming system. The transgene-free iPSC showed pluripotency confirmed by immunofluorescent staining for pluripotency markers and differentiated into the 3 germ layers in vivo. The iPSC line also showed normal karyotype. This cellular model can complement in vivo PD models for pathophysiological studies and drug screening.
外周血单个核细胞(PBMCs)取自一名临床诊断为帕金森病(PD)的64岁男性患者,该患者LRRK2基因存在N551K变异。使用仙台病毒重编程系统,利用人类OSKM转录因子对PBMCs进行重编程。通过对多能性标志物的免疫荧光染色证实,无转基因的诱导多能干细胞(iPSC)具有多能性,并在体内分化为三个胚层。该iPSC系还显示出正常的核型。这种细胞模型可以补充体内PD模型,用于病理生理学研究和药物筛选。
