Abstract

Although arteries and atherosclerotic plaques are three-dimensional structures, the evaluation of plaque size and morphology in preclinical models of atherosclerosis is typically performed in two dimensions by histological analysis. Here, we describe a method to visualize arteries and atherosclerotic plaques in three dimensions. This method combines AdipoClear, a procedure that achieves whole tissue immunolabeling and clearing, and light-sheet fluorescence microscopy, which generates a three-dimensional reconstruction of vessel architecture including atherosclerotic lesions if present. This approach reveals the volume, geometry, acellular component and surface of atherosclerotic plaques as well as the spatial position of the lesion in relation to the affected artery.
