Abstract

The liver microenvironment contains a wide variety of monocyte and macrophage populations. Here, we present a protocol for the specific isolation of liver-resident macrophages, known as Kupffer cells (KCs), from human liver resections. We describe steps for dissociating human liver tissues, separating non-parenchymal cells into fractions by a 2-phase iodixanol gradient, and positive selection of KCs based on the expression of CD163. We then provide instructions for validating the procedure by immunofluorescence to detect CD163. For complete details on the use and execution of this protocol, please refer to Roca Suarez, Plissonnier, et al..

摘要

肝脏微环境包含多种单核细胞和巨噬细胞群体。在此，我们展示了一种从人类肝脏切除组织中特异性分离肝脏驻留巨噬细胞（即库普弗细胞，KCs）的方案。我们描述了将人类肝脏组织解离、通过两相碘克沙醇梯度将非实质细胞分离成不同组分以及基于CD163表达对KCs进行阳性分选的步骤。然后，我们提供了通过免疫荧光检测CD163来验证该程序的说明。有关此方案的使用和执行的完整详细信息，请参考罗卡·苏亚雷斯、普利索尼耶等人的研究。
