[Abstract]  Induced pluripotent stem cell derived cardiovascular progenitor cells (iPSC-CVPCs) provide an unprecedented platform for examining the molecular underpinnings of cardiac development and disease etiology, but also have great potential to play pivotal roles in the future of regenerative medicine and pharmacogenomic studies. Biobanks like iPSCORE ( Stacey et al., 2013; Panopoulos et al., 2017), which contain iPSCs generated from hundreds of genetically and ethnically diverse individuals, are an invaluable resource for conducting these studies. Here, we present an optimized, cost-effective and highly standardized protocol for large-scale derivation of human iPSC-CVPCs using small molecules and purification using metabolic selection. We have successfully applied this protocol ... [摘要]  [摘要 ] 诱导性多能干细胞衍生的心血管祖细胞(iPSC-CVPCs)为检查心脏发育和疾病病因的分子基础提供了前所未有的平台,但在再生医学和药物基因组学的未来中也具有重要作用。像iPSCORE这样的生物库(Stacey 等,2013 ;Panopoulos 等,2017), 其中包含由数百个遗传和种族不同的个体产生的iPSC,是进行这些研究的宝贵资源。在这里,我们为小分子大规模衍生人iPSC-CVPCs和代谢选择纯化提供了一种优化,具有成本效益和高度标准化的方案。我们已经成功地应用了该协议,从154种不同的iPSCORE iPSC品系中获得了iPSC-CVPC,从而获得了大量的高纯度心脏细胞。一个重要的我们的协议的组成部分是Ç ELL Ç onfluency 估计S(ccEstimate ),用于估计当iPSC集单层将达到80%汇合,这是用于发起的iPSC-CVPC推导最佳的时间的自动方法,并且使得协议为易于在具有不同增长率的iPSC系列中使用。此外,我们发现跨iPSC-CVPC的细胞异质性是由于两种截然不同的心脏细胞类型(心肌细胞(CMs)和心外膜衍生细胞(EPDCs))的比例不同导致的,这两种细胞在心脏再生中均具有关键作用。该协议消除了iPSC线到线优化的需要,并且可以轻松地进行调整和扩展,以进行高通量研究或生成大量适用于再生医学应用的细胞。

Generation of T cells from Human and Nonhuman Primate Pluripotent Stem Cells

[Abstract]  Pluripotent stem cells (PSCs) have the potential to provide homogeneous cell populations of T cells that can be grown at a clinical scale and genetically engineered to meet specific clinical needs. OP9-DLL4, a stromal line ectopically expressing the Notch ligand Delta-like 4 (DLL4) is used to support differentiation of PSCs to T-lymphocytes. This article outlines several protocols related to generation of T cells from human and non-human primate (NHP) PSCs, including initial hematopoietic differentiation of PSC on OP9 feeders or defined conditions, followed by coculture of the OP9-DLL4 cells with the PSC-derived hematopoietic progenitors (HPs), leading to efficient differentiation to T lymphocytes. In addition, we describe a protocol for robust T cell generation from hPSCs conditionally ... [摘要]  [摘要] 多能干细胞(PSCs)有潜力提供同质的T细胞群体,这些细胞可以在临床规模上生长,并通过基因工程来满足特定的临床需求。OP9-DLL4是一种异位表达Notch配体Delta-like 4(DLL4)的基质细胞系,用于支持psc向T淋巴细胞的分化。本文概述了从人类和非人类灵长类(NHP)PSC中产生T细胞的几种方法,包括在OP9喂食者或特定条件下对PSC进行初始造血分化,然后将OP9-DLL4细胞与PSC衍生的造血祖细胞(HPs)共培养,从而有效地分化成T淋巴细胞。此外,我们描述了一个从有条件表达ETS1的hPSCs中产生健壮T细胞的方案。所提出的协议提供了一个平台,用于疾病建模和评估其在大型动物模型免疫治疗中的应用。

[背景] T淋巴细胞(T细胞)在细胞介导的免疫反应中起着关键作用,参与肿瘤细胞的监测和杀伤。在过去的几十年里,已经开发了几种策略来重定向、培养和/或增强抗肿瘤的T淋巴细胞(Houot等人,2015年;June等人,2018年),并将其用于基于T细胞的过继免疫治疗。最近的临床试验表明,用嵌合抗原受体(CAR)-T细胞治疗复发性和难治性淋巴瘤患者的疗效显著(Riviere和Sadelain,2017)。

人类多能干细胞(hPSCs),包括胚胎(hESCs)和诱导(hiPSCs),为生产用于过继性细胞免疫疗法的T细胞提供了一种很有前景的资源,可与基因工程技术相结合,产生现成的CAR ...
