[Abstract] Coronary artery disease remains an important cause of morbidity and mortality. Previous work, including ours, has focused on the role of intraplaque hemorrhage, particularly from immature microvessel angiogenesis, as an important contributor to plaque progression via increases in vascular permeability leading to further intraplaque hemorrhage, which increases red cell membrane-derived free cholesterol in plaque content and inflammatory cell recruitment. Evans Blue Dye (EBD) assay is widely used as a standard assay for vasculature permeability. However, the method has not been established in ...
[摘要] 冠状动脉疾病仍然是发病率和死亡率的重要原因。以前的研究，包括我们的研究，都集中在斑块内出血的作用，特别是来自未成熟的微血管血管生成，作为斑块进展的重要因素，通过增加血管通透性导致进一步的斑块内出血，增加斑块中红细胞膜来源的游离胆固醇内容和炎症细胞募集。 Evans Blue Dye（EBD）测定法广泛用作脉管系统渗透性的标准测定法。然而，该方法尚未在新鲜人冠状动脉尸检样本中建立，以评估斑块内微血管通透性和血管生成。在该方案中，我们描述了评估人类冠状动脉样本的微血管通透性的方法，包括灌注冠状动脉的程序，用于组织学分析和免疫染色的动脉样本的收集以及使用适当的方法来分析图像。还提供了在小鼠模型中使用FITC-葡聚糖以评估血管通透性的任选程序。这些Evans Blue Dye程序可用于在各种病理条件下提供人样品和动物模型中内皮完整性和渗透性的功能测量。
【背景】
血管内皮细胞主动调节血浆成分和循环细胞（包括白细胞）从血液到亚内皮组织的浸润。这种机制通常被认为是动脉粥样硬化起始和发展的关键步骤（Mundi et al。>，2018）。血管通透性的调节通过内皮细胞 - 细胞连接的协调打开和闭合来实现。在几种疾病状态下，内源性药物如组胺，凝血酶和血管内皮生长因子（VEGF）显着但可逆地以不同方式改变细胞 - ...

[Abstract] Myometrium forms the middle layer of the uterus and is mainly composed of the smooth muscle cells. The cells in vitro are usually grown in a single layer (2-dimensional; 2D) format, whereas in vivo cells are structured in an extracellular matrix scaffolding that allows the cells to communicate and respond to environmental cues. We have developed human myometrium and leiomyoma 3-dimensional (3D) culture, wherein the cells retain their molecular characteristics and respond to environmental cues (Malik and Catherino, 2012; Malik et al., 2014).
[摘要] 子宫肌层形成子宫的中间层，主要由平滑肌细胞组成。细胞在体外通常生长在单层（2维; 2D）格式中，而体内细胞在细胞外基质支架中结构化，其允许细胞沟通和响应环境线索。我们已经开发了人子宫肌瘤和平滑肌瘤3维（3D）培养物，其中细胞保留其分子特征并响应环境线索（Malik和Catherino，2012; Malik等人，2014）。 br /> [背景] 在过去十年中，随着更多实验室从使用人工2D格式的细胞培养转移到3D细胞培养模型系统，观察到一定的转变，其中细胞生长在允许它们附着并获得更生理结构的基质中。该模型系统为细胞提供更自然的分化状态，并且培养的细胞在体内形成组织样环境。这是一个详细的协议为myometrium 3D细胞培养生长胶原-1矩阵，修改从Malik和Catherino（2012年）。

[Abstract] The aim of this protocol is to provide a comprehensive description of the materials, equipment and reproducible methods to detect and analyze anaphase bridges in immunofluorescence microscopy using DAPI to detect cells that failed to completely segregate during mitosis. It describes the process of cell preparation, staining and microscopic settings for detection of anaphase bridges. The protocol has been adapted from our previous publication (Aschacher et al., 2016).
