[Abstract]  Macrophages maintain tissue homoeostasis by regulating inflammation and tissue repair mechanisms. Thus, the fate of macrophages has an impact on the state of the tissue. The aim of this protocol is to quantify macrophage survival using high content microscopy and image processing software. Here, we describe a high-content image based protocol to assess the effect of diverse stimuli in combination with pharmacological treatments on macrophage survival in a quantitative, unbiased and high-throughput manner. [摘要]  巨噬细胞通过调节炎症和组织修复机制来维持组织均匀平衡。 因此,巨噬细胞的命运对组织的状态有影响。 该方案的目的是使用高含量显微镜和图像处理软件来量化巨噬细胞存活。 在这里,我们描述了一种基于高含量图像的方案,以定量,无偏差和高通量方式评估不同刺激与药理学治疗对巨噬细胞存活的影响。
【背景】巨噬细胞是吞噬先天免疫细胞,是组织炎症的主要驱动因素(Medzhitov,2008)。 这些细胞与自身免疫,自身炎症,感染性,神经变性和代谢性疾病一起与癌症相关(Ginhoux和Jung,2014)。 在这种情况下,巨噬细胞在炎症中的作用得到了很好的研究,然而,非传染性和感染性疾病中巨噬细胞存活的影响在很大程度上是未知的。 我们的研究表明,某些病原体相关受体(PRR)的激活可以诱导巨噬细胞存活(Eren等,2016)。 我们描述了一种分子机制,证明专门的细胞内病原体如何利用PRR诱导的细胞存活(Eren等,2016)。 因此,需要进一步的研究来了解巨噬细胞存活在不同疾病环境中的作用。

Lentiviral Barcode Labeling and Transplantation of Fetal Liver Hematopoietic Stem and Progenitor Cells

[Abstract]  Cellular barcoding enables the dissection of clonal dynamics in heterogeneous cell populations through single cell lineage tracing. The labeling of hematopoietic stem and progenitor cells (HSPCs) with unique and heritable DNA barcodes, makes it possible to resolve donor cell heterogeneity in terms of differentiation potential and lineage bias at the single cell level, through subsequent transplantation and high-throughput sequencing. Furthermore, cellular barcoding allows for bona fide hematopoietic stem cells (HSCs) to be defined based on functional rather than immunophenotypic parameters.

This protocol describes the work flow of lentiviral cellular barcoding, tracking 14.5 days post coitum (d.p.c.) fetal liver (FL) Lineage-Sca+cKit+ (LSK) HSPCs following ...
[摘要]  细胞条形码可以通过单细胞谱系追踪来分离异种细胞群体中的克隆动力学。通过独特和可遗传的DNA条形码对造血干细胞和祖细胞(HSPC)进行标记,可以通过随后的移植和高通量测序,在单细胞水平上分化供体细胞异质性,分化潜力和谱系偏倚。此外,细胞条形码可以根据功能而不是免疫表型参数定义真正的造血干细胞(HSC)。
 该协议描述了慢病毒细胞条形码的工作流程,追踪1450天后(dpc)胎肝(FL)Lineage-Sca+ cKit + (LSK)HSPC经过长期重建(图1)(Kristiansen等人,2016),但可以适应于选择的细胞类型或时间框架。

最初建立了细胞条形码技术来解决在体内移植造血细胞后的单细胞动力学,并且近年来在移植中对血细胞群体中功能​​异质性的认识有显着贡献(Schepers ,2008; Gerrits等人,2010; Lu等人,2011; Naik等人 ,2013; Verovskaya等人,2013; ...

Detection of Reactive Oxygen Species Using MitoSOX and CellROX in Zebrafish

[Abstract]  The production of free radicals is the result of normal cellular metabolism. Free radicals are involved in innumerable different cellular and biological functions such as signaling, proliferation, cell death, aging, inflammation, etc. Under physiological conditions, the levels of reactive oxygen species (ROS) are strictly regulated by the cells. However, during stressful conditions such as oxidative stress, ROS levels increase causing damages to different molecules like DNA, lipids and proteins. Increased levels of ROS have been associated with a growing list of different diseases. In this protocol, we used MitoSOX and CellROX Green oxidative stress probes to label the intracellular ROS and detect the fluorescence using cell sorting and confocal analyses. [摘要]  自由基的产生是正常细胞代谢的结果。 自由基涉及无数不同的细胞和生物学功能,例如信号传导,增殖,细胞死亡,衰老,炎症等。 在生理条件下,活性氧(ROS)的水平被细胞严格调节。 然而,在应激条件例如氧化应激期间,ROS水平增加导致对不同分子如DNA,脂质和蛋白质的损伤。 增加的ROS水平与不断增加的不同疾病列表相关联。 在这个协议中,我们使用MitoSOX和CellROX绿色氧化应激探针标记细胞内ROS和使用细胞分选和共聚焦分析检测荧光。
