S100A4 and atherosclerosis: Recent observations in the animal models of atherosclerosis have reported the existence of a repertoire of cells that express both mesenchymal markers (α-SMA, Snail, Vimentin, and FSP1 (S100A4)), as well as endothelial markers (VE-cadherin, PECAM-1, and Endocan), indicating a considerable endothelial origin of the neointimal cells, which may differentiate into myofibroblasts.
