An Image-based Dynamic High-throughput Analysis of Adherent Cell Migration

[Abstract]  

In this protocol, we describe a method to monitor cell migration by live-cell imaging of adherent cells. Scratching assay is a common method to investigate cell migration or wound healing capacity. However, achieving homogenous scratching, finding the optimal time window for end-point analysis and performing an objective image analysis imply, even for practiced and adept experimenters, a high chance for variability and limited reproducibility. Therefore, our protocol implemented the assessment for cell mobility by using homogenous wound making, sequential imaging and automated image analysis. Cells were cultured in 96-well plates, and after attachment, homogeneous linear scratches were made using the IncuCyte® WoundMaker. The treatments were added directly to wells and images were

[摘要]  [摘要]在此协议中,我们描述了一种通过贴壁细胞的活细胞成像监测细胞迁移的方法。刮擦测定法是研究细胞迁移或伤口愈合能力的常用方法。然而,实现均匀的scratc兴,发现为终点analys的最佳时间窗口我S和执行目标图像分析暗示,即使对于实施,并且熟练的实验者,对变异性和有限的再现性的高机会。因此,我们的协议通过使用均质伤口制作,顺序成像和自动图像分析来实现对细胞移动性的评估。细胞在96孔板中培养,和附着后,使用进行了由均质线状痕INCUCYTE ® W¯¯ oundMaker 。将处理直接添加到孔中,每2小时自动捕获一次图像。Ť此后,对图像进行的ProCE ssed通过定义刮擦掩模,并使用细胞汇合掩模软件算法。数据分析是进行使用的INCUCYTE ®细胞迁移分析软件。因此,我们的协议允许以高度可靠,可再现和可重新分析的方式对细胞迁移的治疗效果进行时滞分析。


[背景]划痕测定小号是用于研究细胞迁移一种广泛使用的方法或伤口愈合的能力。然而,常规方法(手动刮擦)需​​要技能来执行线性刮擦并且是终点测定(Liang等人,2007 ;Krishnamurthy等人,2016)。通常使用Ima geJ或其他软件手动分析数据。最近,我们在细胞迁移测定中采用了Essen Bioscience的高通量自动成像系统IncuCyte ZOOM ...

[Abstract]  In this protocol, we describe our methods to isolate crypts from patients' biopsy samples and to culture human intestinal stem cells as it’s called “organoid.” Beyond that, we describe how to dissociate organoids cells into single cells for single-cell analysis as a further application. This protocol should provide investigators sufficient tools to generate human organoids from biopsy samples and to accomplish a stable in-vitro assay system. [摘要]  [摘要]在此协议中,我们描述了从患者的活检样本中分离隐窝并培养人类肠干细胞(称为“类器官”)的方法。除此之外,我们还介绍了如何将类器官细胞分解为单细胞以进行单细胞分析,作为进一步的应用。该方案应为研究人员提供足够的工具,以从活检样品中产生人类器官并完成稳定的体外测定系统。

[背景]肠上皮是一个多功能组织即编排动态平衡并形成物理屏障。由肠干细胞(ISC)产生的每个肠上皮细胞(IEC)每4-5天更新一次该上皮(Crosnier等,2006 )。ISC位于隐窝的底部,并表达各种文献先前报道的特定标记(Muñoz等,2012 ;Clevers ,2013 )。研究表明,干细胞正确更新的功能障碍与肠道疾病有关,对ISCs动态的了解可能阐明了包括炎症性肠病(IBD)在内的各种疾病的发病机制(Okamoto et al。,2016 )。

然而,由于缺乏能概括生理性肠上皮层的有效模型,因此对肠干细胞特性的研究具有挑战性。史诗般的“类器官”的引入克服了种种障碍(Sato等人,2009和2011 ),可以从单个ISC体外建立类器官,并忠实地保留其起源组织的生理和病理特征(Middendorp等人)。 。,2014 )。类器官已被用于各种胃肠道疾病解剖基础病理变化(Fatehullah 。等人,2016; Noben等人,2017 ...
