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 ... [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, / ...

FACS-based Isolation of Neural and Glioma Stem Cell Populations from Fresh Human Tissues Utilizing EGF Ligand

[Abstract]  Direct isolation of human neural and glioma stem cells from fresh tissues permits their biological study without prior culture and may capture novel aspects of their molecular phenotype in their native state. Recently, we demonstrated the ability to prospectively isolate stem cell populations from fresh human germinal matrix and glioblastoma samples, exploiting the ability of cells to bind the Epidermal Growth Factor (EGF) ligand in fluorescence-activated cell sorting (FACS). We demonstrated that FACS-isolated EGF-bound neural and glioblastoma populations encompass the sphere-forming colonies in ... [摘要]  从新鲜组织中直接分离人类神经和胶质瘤干细胞允许其在没有事先培养的情况下进行生物学研究,并且可以在其天然状态中捕获其分子表型的新方面。最近,我们展示了前瞻性地从新鲜人类生发基质和胶质母细胞瘤样品中分离干细胞群的能力,利用细胞在荧光激活细胞分选(FACS)中结合表皮生长因子(EGF)配体的能力。我们证明FACS分离的EGF结合的神经和成胶质细胞瘤细胞群体在体外包含球体形成的集落,并且能够自我更新和多向分化。在此我们详细描述了具有来自新鲜死亡和手术组织的干细胞特性的EGF-结合(即EGFR +)人类神经和胶质瘤细胞的纯化方法。利用天然配体结合能力前瞻性分离干细胞群的能力为了解非培养条件下的正常和肿瘤细胞生物学打开了新的门,并且适用于在种群和单细胞分辨率下的各种下游分子测序研究。

【背景】由于缺乏通用的神经和神经胶质瘤干细胞标志物(Lathia et al。,2015)以及频繁依赖于培养的细胞,理解人神经和胶质瘤干细胞的内在生物学一直是一个挑战比那些直接从组织分离的。跨膜糖蛋白Prominin或CD133是分离神经(Uchida等,2000)和神经胶质瘤干细胞(GSC)(Singh等,2000)的最好描述和经常使用的干细胞标记物之一。等人,2003; Singh等人,2004; ...

Isolation, Culture and Differentiation of Primary Acinar Epithelial Explants from Adult Murine Pancreas

[Abstract]  The adult pancreas possesses an intrinsic developmental plasticity whereby acinar cells can convert into ductal structures under some pathological conditions. Acinar tissue can be isolated from murine pancreas and kept in three-dimensional collagen culture. Acinar to ductal metaplasia can be induced in primary acinar epithelial explants by treatment with growth factors. This method can be utilized in ex vivo studies involving pancreatic epithelial differentiation. [摘要]  成人胰腺具有固有的发育可塑性,其中腺泡细胞可以在一些病理条件下转化为导管结构。 腺泡组织可以从鼠胰腺中分离并保存在三维胶原培养物中。 腺泡到导管化生可以通过用生长因子治疗在原发性腺泡上皮外植体中诱导。 该方法可以用于涉及胰腺上皮分化的离体研究。
