Analyzing the Quenchable Iron Pool in Murine Macrophages by Flow Cytometry

[Abstract]  Tissue-resident macrophages are pivotal for a tightly-regulated iron metabolism at a cellular and systemic level, since subtle iron alterations increase the susceptibility for microbial infections or drive multiple diseases. However, research on cellular iron homeostasis in macrophages remains challenging due to the limited amount of available methods using radioactive 59Fe isotopes or strong iron chelators, which might be inapplicable in certain experimental settings. This protocol describes the analysis of the quenchable iron pool (QIP) in macrophages by loading these cells with exogenous iron-complexes. Thereby, the cytoplasmic iron pool can be determined, since the iron uptake ability of macrophages inversely correlates with intracellular iron levels. Thus, this assay ... [摘要]  [摘要 ] 驻留在组织中的巨噬细胞对于在细胞和全身水平上严格调节铁代谢至关重要,因为细微的铁改变会增加对微生物感染的敏感性或引发多种疾病。然而,由于使用放射性59 Fe同位素或强铁螯合剂的可用方法数量有限,因此巨噬细胞中细胞铁稳态的研究仍然具有挑战性,这在某些实验环境中可能不适用。该协议 描述了通过向这些细胞加载外源铁配合物来分析巨噬细胞中的可淬灭铁池(QIP)。因此,由于巨噬细胞的铁摄取能力与细胞内铁水平成反比,因此可以确定细胞质的铁库。因此,该测定法能够准确分析细胞质铁通量的微小变化,并且几乎适用于所有实验室环境。另外,该方案还可以用于体外和体内的其他免疫细胞类型。

[背景 ] 由于用于全身铁代谢它们的中心调节功能,在多种组织中的巨噬细胞中迅速地改变在不同的刺激的遭遇它们的细胞内的铁水平的微生物感染和疾病(Nairz 等人,2017) 。值得注意的是,大多数细胞中的铁离子被细胞质中的主要铁存储蛋白铁蛋白结合或定位于线粒体或溶酶体等区室(Ma 等,2015 ; Soares和Hamza,2016 ...

[Abstract]  The isolation and primary culture of cells from human endometrial biopsies provides valuable experimental material for reproductive and gynaecological research. Whole endometrial biopsies are collected from consenting women and digested with collagenase and DNase I to dissociate cells from the extracellular matrix. Cell populations are then isolated through culturing, filtering and magnetic separation using cell-surface antigen markers. Here we provide a comprehensive protocol on how to isolate and culture individual cell types from whole endometrial tissues for use in in vitro experiments. [摘要]  从人子宫内膜活组织检查中分离和原代培养细胞为生殖和妇科研究提供了有价值的实验材料。从同意的妇女收集完整的子宫内膜活检组织并用胶原酶和DNA酶I消化以从细胞外基质中分离细胞。然后通过使用细胞表面抗原标记物的培养,过滤和磁性分离来分离细胞群。在这里,我们提供了如何从整个子宫内膜组织分离和培养个体细胞类型以用于体外实验的全面方案。

[背景] 人子宫内膜是子宫内层最粘的层。其由柱状上皮和基础基质层组成,其经历循环再生,生长和响应于循环激素的转化。子宫内膜衬里分化为腺分泌表型为囊胚植入和成功怀孕提供了一个好客的环境。在没有怀孕这个层脱落,导致月经。从人子宫内膜活组织检查中分离和培养细胞允许在体外功能评估和与患者结果相关的细胞特征的研究。子宫内膜细胞的分离和培养是研究妇科和产科医学的许多方面的非常宝贵的研究模型,包括不孕,植入失败,复发性流产和月经紊乱。全人子宫内膜活检包含人子宫内膜基质细胞(HESCs),腔和子宫内膜上皮细胞(HEEC),红细胞和免疫细胞的混合群体。 ...
