[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, / ...
