Myocardial infarction (MI) is a leading cause of death worldwide. Permanent ligation of the left anterior descending coronary artery (LAD) is a commonly used surgical model to study post-MI effects in mice. LAD occlusion induces a robust wound healing response that includes extracellular matrix (ECM) remodeling. This chapter provides a detailed guide on the surgical procedure to permanently ligate the LAD. Additionally, we describe a prototype method to enrich cardiac tissue for ECM, which allows one to focus on ECM remodeling in the left ventricle following surgically induced MI in mice.
心肌梗死(MI)是全球范围内主要的死亡原因。永久性结扎左冠状动脉前降支(LAD)是研究小鼠心肌梗死后效应常用的手术模型。LAD闭塞会引发强烈的伤口愈合反应,其中包括细胞外基质(ECM)重塑。本章提供了关于永久性结扎LAD手术过程的详细指南。此外,我们描述了一种富集心脏组织中ECM的原型方法,该方法能使人们专注于小鼠手术诱导心肌梗死后左心室的ECM重塑。
