Foam cells, also called lipid-laden macrophages, are a type of cell that contain cholesterol. These can form a plaque that can lead to atherosclerosis and trigger myocardial infarction and stroke.[1][2][3]
Foam cells are fat-laden cells with a M2 macrophage-like phenotype. They contain low density lipoproteins (LDL) and can be rapidly detected by examining a fatty plaque under a microscope after it is removed from the body.[4] They are named because the lipoproteins give the cell a foamy appearance.[5]
Despite the connection with cardiovascular diseases they might not be inherently dangerous.[6]
Some foam cells are derived from smooth muscle cells and present a limited macrophage-like phenotype.[7][8][9]
