Induced pluripotent stem cells (iPSCs) hold tremendous potential both as a biological tool to uncover the pathophysiology of disease by creating relevant cell models and as a source of stem cells for cell-based therapeutic applications. Typically, iPSCs have been derived by the transgenic overexpression of transcription factors associated with progenitor cell or stem cell function in fibroblasts derived from skin biopsies. However, the need for skin punch biopsies to derive fibroblasts for reprogramming can present a barrier to study participation among certain populations of individuals, including children with autism spectrum disorders (ASDs). In addition, the acquisition of skin punch biopsies in non-clinic settings presents a challenge. One potential mechanism to avoid these limitations would be the use of peripheral blood mononuclear cells (PBMCs) as the source of the cells for reprogramming. In this article we describe, for the first time, the derivation of iPSC lines from PBMCs isolated from the whole blood of autistic children, and their subsequent differentiation in GABAergic neurons.
诱导多能干细胞 (iPSC) 作为一种生物工具,具有巨大的潜力,可以通过创建相关的细胞模型来揭示疾病的病理生理学,也可以作为基于细胞的治疗应用的干细胞来源。通常,iPSC 是通过在皮肤活检衍生的成纤维细胞中转基因过表达与祖细胞或干细胞功能相关的转录因子来获得的。然而,为了对源自皮肤活检的成纤维细胞进行重编程,需要皮肤穿刺活检,这可能会成为某些人群(包括自闭症谱系障碍 (ASD) 儿童)参与研究的障碍。此外,在非临床环境中采集皮肤穿刺活检也存在挑战。一种潜在的避免这些限制的机制是使用外周血单核细胞 (PBMC) 作为重编程细胞的来源。在本文中,我们首次描述了从自闭症儿童全血中分离的 PBMC 中获得 iPSC 系,并随后分化为 GABA 能神经元。
