Exit from Pluripotency Assay of Mouse Embryonic Stem Cells

[Abstract]  A novel method to assess the dissolution of the core pluripotency transcription-factor circuit of mouse Embryonic Stem Cells (mESCs) has been developed (Ying et al., 2003; Betschinger et al., 2013). In order to efficiently identify genes essential for the break-down of the pluripotency network in mutant mESCs with proliferation defects, we adapted this ‘exit from pluripotency assay’ (Bodak et al., 2017; Cirera-Salinas et al., 2017). The protocol described here has been successfully applied to several mESC lines and is easily transposable from one laboratory ... [摘要]  已经开发了评估小鼠胚胎干细胞(mESCs)的核心多能转录因子电路溶解的新方法(Ying等,2003; Betschinger等,2013)。 为了有效识别具有增殖缺陷的突变体mESCs中多能网络分解所必需的基因,我们调整了这种“多能性测定法”(Bodak等,2017; Cirera-Salinas等,2017)。 这里描述的方案已经成功应用于几个mESC系列,并且可以容易地从一个实验室转座到另一个实验室。
【背景】几十年来,科学家已经尝试确定基因与一般(例如胚胎体)或定向(例如,神经元前体细胞)分化方案的mESCs的分化潜能的机制。最近,发现2i培养基允许在体外俘获天真的干细胞(Ying et al。,2008)。 ...

[Abstract]  Pluripotent stem cells in the naïve state are highly useful in regenerative medicine and tissue engineering. A robust reprogramming of the primed murine Epiblast Stem Cells (EpiSCs) to naïve pluripotency is feasible via chemical-only approach. This protocol described a method to reprogram murine EpiSCs by MM-401 treatment, which blocks histone H3K4 methylation by MLL1/KMT2A. [摘要]  初生状态下的多能干细胞在再生医学和组织工程中非常有用。 通过化学方法,将引发的鼠上皮细胞干细胞(EpiSCs)的鲁棒重新编程成为初始多能性是可行的。 该方案描述了通过MM-401处理重编程小鼠EpiSCs的方法,其通过MLL1 / KMT2A阻断组蛋白H3K4甲基化。

背景 以前关于EpiSC重编程的方案取决于转录因子的遗传操作或信号通路的化学抑制,尽管效率和持续时间不同。 基于最近将MLL1复合物与初始状态联系起来的机制研究,该方案提供了一种直观而有力的方法,通过靶向MLL1介导的H3K4甲基化和随后的转录调节来恢复EpiSC的初始多能性。 重编程效率明显高于以前公布的方法,在两周内达到50%的转化率。

[Abstract]  Groundbreaking studies from Dr. Yoshiki Sasai’s laboratory have recently introduced novel methods to differentiate mouse and human Embryonic Stem Cells (mESCs and hESCs) into organ-like 3D structures aimed to recapitulate developmental organogenesis programs (Eiraku et al., 2011; Eiraku and Sasai, 2012; Nakano et al., 2012; Kamiya et al., 2011). We took advantage of this method to optimize a 3D protocol to efficiently generate retinal progenitor cells and subsequently retinal neurons in vitro. This culture system provides an invaluable platform both to ... [摘要]  来自Yoshiki Sasai博士的实验室的开创性研究最近已经引入了将小鼠和人胚胎干细胞(mESC和hESC)区分为器官样3D结构的新方法,其旨在重现发育器官发生程序(Eiraku等人, ,2011; Eiraku和Sasai,2012; Nakano等人,2012; Kamiya等人,2011)。 我们利用这种方法优化3D协议以有效地生成视网膜祖细胞和随后视网膜神经元体外。 这种文化系统提供了一个宝贵的平台,既研究早期发展过程,并获得视网膜神经元的移植方法。 这里描述的协议已成功应用于几个鼠标ESC(包括R1,WD44和G4细胞系)和小鼠诱导多能干细胞(iPSCs)线。
