将FeCl3局部应用于脉管系统以诱导血栓形成是一种广泛使用的技术，并且有助于建立各种血小板受体，配体信号通路及其抑制剂的作用20，21，22，23。FeCl3引起血栓形成的机制是多方面的;以前，内皮剥蚀被认为是血栓形成的原因，然而近年来，多份报告表明红细胞和血浆蛋白在此过程?...

血栓形成是部分或完全阻塞血管的血凝块的形成，阻碍血液的自然流动。这会导致严重和致命的心血管事件，如缺血性心脏病和中风。心血管疾病是发病和死亡的主要原因，导致全世界四分之一的死亡1，2，3。虽然血栓形成表现为血管系统功能障碍，但它可能是潜在的微生物或病毒感染、免疫紊乱、恶性肿瘤或代谢疾病的结果。血液流动由血管系统不同组成部分（包括内皮细胞、红/白细胞、血小板和凝血因子）之间的复杂相互作用维持4.血管损伤后，血小板与内皮下基质上的粘附蛋白相互作用并释放其颗粒内容物，从而募集更多的血小板5。同时，凝血级联反应被激活，导致纤维蛋白形成和沉积。最终，形成凝块，包含被困在纤维蛋白网内的血小板和红细胞6。虽然抗血小板和抗凝药物可用于调节血栓形成，但假性出血仍然是这些疗法的主要问题，需要微调这些药物的剂量和组合。因此，仍然迫切需要发现新的抗血栓药物7。
使用多种方法研究血栓形成以造成血管损伤：机械（血管结扎），热损伤（激光损伤）和化学损伤（FeCl3 / Rose Bengal应用）。血栓形成的性质因损伤部位（动脉与静脉）、损伤方法或程度而异。在所有这些类型中，FeCl3诱导的血管损伤是最广泛使用的方法。它已被用于小鼠，大鼠，兔子，豚鼠和狗8，9，10，11，12。该方法相对简单，易于使用，如果主要参数标准化，则在各种血管系统（例如动脉[颈动脉和股动脉]，静脉[颈动脉]和小动脉[提睾和肠系膜]）中具有敏感性和可重复性（补充表1）。
该模型也可用于进一步了解凝块形成的机制和形态。该技术独特地提供了在不同流速点阻止血栓形成的优势，以在过程闭塞之前研究该过程的中间阶段。血栓形成研究的最新进展使用该模型将注意力集中在溶栓的非药物方法13 或抗血栓和/或纤维蛋白溶解剂的非侵入性递送14，15上。一些研究小组已经表明，当血小板膜涂有这些疗法时，药物可以在热刺激下被激活以靶向凝块16。这里描述的技术可用于在单个血小板水平验证其发现等研究。在本手稿中，方案 1 描述了基本的 FeCl3 介导的血管损伤程序，而方案 2 描述了收集和固定血管损伤样本以通过电子显微镜进一步分析的方法。

ferric chloride-induced arterial thrombosis and sample collection for 3d electron microscopy analysis

心血管疾病是全世界死亡和发病的主要原因。异常血栓形成是糖尿病和肥胖等全身性疾病以及动脉粥样硬化、癌症和自身免疫性疾病等慢性炎症性疾病的共同特征。血管损伤时，凝血系统、血小板和内皮通常以协调的方式发挥作用，通过在损伤部位形成凝块来防止出血。这一过程中的异常导致出血过多或血栓形成不受控制/抗血栓形成活性不足，这转化为血管闭塞及其后遗症。FeCl3诱导的颈动脉损伤模型是探索血栓形成如何在 体内启动和进展的宝贵工具。该模型涉及内皮损伤/剥落以及随后在受伤部位形成凝块。它提供了一种高度灵敏的定量测定，以监测不同程度的血管损伤和凝块形成。一旦优化，这种标准技术可用于研究血栓形成的分子机制，以及生长中的血栓中血小板的超微结构变化。该测定也可用于研究抗血栓形成和抗血小板药物的疗效。本文解释了如何启动和监测FeCl3诱导的动脉血栓形成，以及如何收集样品通过电子显微镜进行分析。

数据通常表示为闭塞时间，或形成完全闭塞血栓所需的时间。这些数据可以绘制为Kaplan-Meier生存曲线（图4A）19，带有条形图的点图，显示血流停止或实验终止时的最终血流（图4B），或折线图（图4C）。可以使用这种技术研究血栓稳定性。在大多数情况下，在FeCl3损伤时，血栓逐渐形成，随着其生长，血?...

Ferric Chloride-Induced Arterial Thrombosis and Sample Collection for 3D Electron Microscopy Analysis

本协议描述了如何使用FeCl3介导的损伤来诱导动脉血栓形成，以及如何在血栓形成的各个阶段收集和制备动脉损伤样品以进行电子显微镜分析。

使用这种方法，可以确定血小板和止血系统的哪些成分对血栓形成很重要。此外，该方法可以确定血栓生长和结构如何在细胞水平上受到影响。该技术的主要优点是它允许在结构水平上研究血栓形成的许多阶段的可重复方法。刚接触这种技术的人应该避免过度处理手术区域的组织。这可能导致出血，并使颈动脉的识别过于复杂。暴露颈动脉后，通过松散地包围两个尺寸为 0.1 毫米的手术线之间的区域来标记损伤部位。将探头放在下线远端动脉下方。将塑料片插入两条线之间的动脉下方，以标记氯化铁损伤部位。在进行损伤之前进行流量测量，以注意基础血流。通过将氯化铁浸泡的滤纸放在动脉上三分钟来进行损伤。三分钟后取下滤纸，以防止不同程度的伤害，并便于探头进行流量计数。在损伤部位添加生理盐水以去除多余的残留氯化铁。监控流量读数。当流量降至初始值的 50% 以下时，取下探头。快速擦干该区域并添加固定剂以在外部固定损伤区域。接下来，立即用镊子握住损伤区域附近的动脉。在下螺纹的下游和上螺纹的上游切割。将组织以与收集的方向相同的方向放在塑料组织培养皿上，并加入几滴固定剂。使用手术刀清洁动脉周围的多余组织。确保通过水平切割一端和另一端逐渐变细或倾斜来记录血流的方向。将样品在室温下放入固定剂中一小时，然后将样品储存在4摄氏度的1%多聚甲醛中，直到将其送入湿冰进行电子显微镜分析。数据被绘制为Kaplan-Meier生存曲线，一个带有条形图的点图，显示血流停止或实验终止时的最终血流，或作为折线图。在某些情况下，血流量在逐渐减少几分钟后突然增加，表明正在生长的血栓部分脱落，被认为是栓塞事件。使用这种方法也研究了闭塞性血栓形态。在血栓形成过程中及时收集样本是最重要的一步，因为该过程的延迟可能会导致对我们的结构分析的误解。
