In vitro modeling of myocardial ischemia/reperfusion injury with murine or human 3D cardiac spheroids

Abstract

Summary: Myocardial infarction (MI) is the primary cause of death worldwide, but there are no clinically relevant models to study MI. Here, we describe an ischemia/reperfusion (I/R) injury model typical of MI using mouse or human 3D in vitro cardiac spheroids (CSs). First, we demonstrated the culture and maintenance of CSs. Then, we detailed how to expose CSs to pathophysiological oxygen concentrations to induce I/R injury. The protocol can be used in combination with viability, contractility, and mRNA expression level measurements.For complete details on the use and execution of this protocol, please refer to Sharma et al. (2022). : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
