Immunostaining of Macrophages, Endothelial Cells, and Smooth Muscle Cells in the Atherosclerotic Mouse Aorta.

The atherosclerotic mouse aorta consists of a heterogeneous population of cells, including macrophages, endothelial cells, and smooth muscle cells that play critical roles in cardiovascular disease. Identification of these vascular cells in the vessel wall is important to understanding their function in pathological conditions. Immunohistochemistry is an invaluable technique used to detect the presence of cells in different tissues. Here, we describe immunohistochemical techniques commonly used for the detection of the vascular cells in the atherosclerotic mouse aorta using cell type-specific markers.
