Phagocytosis Assay to Measure Uptake of Necroptotic Cancer Cells by BMDCs

[Abstract]  This protocol is a flow cytometry-based method to measure the phagocytosis efficiency of necroptotic target cells by bone marrow-derived dendritic cells (BMDCs) in vitro (Aaes et al., 2016). The method is a slightly modified and updated version of the protocols used in previously published papers (Krysko et al., 2006; Brouckaert et al., 2004). In brief, the target cells are labeled with a CellTrackerTM dye before they are induced to undergo cell death. After a co-culture period of 2 h with BMDCs, the cells are immunostained with a dendritic cell ... [摘要]  该方案是基于流式细胞术的方法,以测量骨髓来源的树突细胞(BMDCs)在体外的坏死性靶细胞的吞噬效率(Aaes等人 2016)。该方法是先前发表的论文中使用的方案的稍微修改和更新的版本(Krysko等人,2006; Brouckaert等人,2004)。简言之,在细胞被诱导经历细胞死亡之前,用CellTracker TM TM染料标记靶细胞。在用BMDCs共培养2小时后,用树突细胞标记物和死细胞标记物对细胞进行免疫染色,并使用流式细胞仪定量吞噬效率。该方案可以容易地用于经历除坏死作用以外的细胞死亡模式的靶细胞。

[背景] 研究BMDCs吞噬细胞摄取的坏死细胞是检测免疫原性细胞死亡模型的初步步骤(Obeid等人,2007)。有效摄取将允许吞噬细胞将抗原交叉呈递到白细胞,从而产生针对死的靶细胞的免疫反应。在该协议中,我们使用CellTracker TM sup TM染料。这种类型的染料在某些浓度下可能是有毒的,其可以根据使用的细胞类型而变化。因此,我们建议用户首先为使用的靶细胞找到最佳的染料浓度。最佳地,CellTracker TM 染料本身不应该诱导任何细胞死亡,而是应当标记靶细胞,使得它们容易与CD11c阳性BMDC分离。

In vitro and in vivo Limiting Dilution Assay for Colorectal Cancer

[Abstract]  The in vitro limiting dilution assay is used to determine the colorectal cancer initiating cell (CC-IC) frequency of a CC-IC enriched suspension culture, grown in growth factor enriched serum free media. The in vivo limiting dilution assay is used to determine the colorectal cancer initiating cell frequency of a primary colorectal cancer sample or an established suspension cell line using immunocompromised murine xenograft models. In vitro and in vivo limiting dilution assays (LDAs) can be used to determine the effect of a specific treatment or genetic ... [摘要]  体外极限稀释测定法用于测定在富含生长因子的无血清培养基中生长的CC-IC富集悬浮培养物的结肠直肠癌起始细胞(CC-IC)频率。 体内限制性稀释测定法用于使用免疫受损的鼠异种移植物模型确定原发性结肠直肠癌样品或建立的悬浮细胞系的结肠直肠癌起始细胞频率。 可以使用体外和体内有限稀释测定法(LDAs)来确定特定处理或遗传击倒策略对CC- IC或结肠直肠癌样品。
