Generation of Chemically Induced Liver Progenitors (CLiPs) from Rat Adult Hepatocytes

[Abstract]  Primary mature hepatocytes (MHs) or their progenitor cells are candidate cell sources for cell transplantation therapy in severe liver diseases. However, stable culture of these cells or generation of equivalent cells from pluripotent stem cells has been limited. Using a cocktail of small molecules that we previously found useful in stable culture of multiple types of stem/progenitor cells, we recently established a novel method to generate bipotent liver progenitor cells, named chemically induced liver progenitors (CLiPs), from adult rat MHs. Here, we describe a detailed protocol for the induction of rat CLiPs. We first describe the method to isolate primary rat MHs and then describe how to induce CLiPs from these MHs. In addition, we describe a method to evaluate the bipotentiality of ... [摘要]  原代成熟肝细胞(MH)或其祖细胞是重症肝病中细胞移植治疗的候选细胞来源。然而,这些细胞的稳定培养或多能干细胞的等效细胞的产生受到限制。我们使用先前在多种类型的干/祖细胞稳定培养中发现有用的小分子混合物,最近建立了一种从成年大鼠MHs产生双能肝脏祖细胞(命名为化学诱导肝祖细胞(CLiPs))的新方法。在这里,我们描述了诱导大鼠CLiPs的详细方案。我们首先描述分离原代鼠MH的方法,然后描述如何从这些MH中诱导CLiPs。另外,我们描述了一种评估产生的CLiPs分化成肝细胞和胆管上皮细胞的双能性的方法。我们还介绍了如何通过长期的文化和详细的示例数据建立稳定的CLiP。可以在2周内产生初级CLiPs,并且可以在2.5-4个月内建立经历10次传代的稳定的CLiPs,批次间变异性。
【背景】对于实现肝病再生医学的新型细胞来源有着强烈的需求。目前唯一的治疗终末期肝病的方法是肝移植,但是由于供者短缺,其应用受到限制。最近,我们小组提出了一种产生能够在体外稳定地扩增的新型LPC的方法,并且可以以广泛的效率重新繁殖慢性肝炎动物模型的损伤肝脏(Katsuda等人, / ...

[Abstract]  Quantitative analysis of proteins secreted from the cells poses a challenge due to their low abundance and the interfering presence of a large amount of bovine serum albumin (BSA) in the cell culture media. We established assays for detection of mutant huntingtin (mHtt) secreted from Neuro2A cell line stably expressing mHtt and rat primary cortical neurons by Western blotting. Our protocol is based on reducing the amounts of BSA in the media while maintaining cell viability and secretory potential, and concentrating the media prior to analysis by means of ultrafiltration. [摘要]  由细胞分泌的蛋白质的定量分析由于它们的丰度低和在细胞培养基中干扰大量牛血清白蛋白(BSA)的存在而提出挑战。 我们建立检测突变亨廷顿蛋白(mHtt)检测分泌Neuro2A细胞系稳定表达mHtt和大鼠原代皮层神经元蛋白质印迹。 我们的方案是基于降低培养基中BSA的量,同时保持细胞活力和分泌潜能,并在通过超滤分析之前浓缩培养基。


【背景】许多蛋白质通过各种分泌途径从细胞分泌到细胞外环境中。这些途径包括在ER-高尔基体 - 质膜途径之后的常规分泌途径(Lee等,2004)和多个非常规途径,例如溶酶体胞吐作用,穿过质膜的易位和外泌体以及胞外体释放(Zhang和Schekman,2013)。为了研究这些途径,经常需要分析培养细胞分泌的蛋白质进入培养基。蛋白质可以游离形式分泌,也可以与胞膜结构如胞外体和外泌体结合(Zhang and ...

[Abstract]  Primary myoblast culture is a valuable tool in research of muscle disease, pathophysiology, and pharmacology. This protocol describes techniques for dissociation of cells from human skeletal muscle biopsies and enrichment for a highly myogenic population by fluorescence-activated cell sorting (FACS). We also describe methods for assessing myogenicity and population expansion for subsequent in vitro study. [摘要]  原代成肌细胞培养是研究肌肉疾病,病理生理学和药理学的有用工具。 该协议描述了通过荧光激活细胞分选(FACS)从人类骨骼肌活检中分离细胞并富集高度肌原细胞的技术。 我们还描述了用于评估随后的体外研究中肌原性和群体扩张的方法。
【背景】来自肌肉活组织检查的原代人成肌细胞是模拟体外人体肌肉疾病的有价值的资源。成肌细胞增殖,分化和融合的改变是许多神经肌肉疾病所共有的特征,并且可以用于测定基于细胞的和药理学的治疗。人类骨骼肌活组织检查,尤其是那些受疾病影响的人,通常含有大量的非肌原细胞,如脂肪细胞和成纤维细胞。因此,纯化肌原细胞进行骨骼肌发育和疾病的体外研究是非常重要的。肌肉疾病的早期研究涉及使用组织外植体或未纯化的分离细胞(Geiger和Garvin,1957; Herrmann等人,1960; Goyle等人,1967; Bishop 1971年),后来,Blau和Webster引入了一种预先电镀技术去除成纤维细胞(Blau and ...
