CCL4L1/platelet factor-4 variant (PF-4var), is a highly angiostatic chemokine1 and a potent regulator of endothelial cell biology, which affects angiogenesis and vascular diseases.2 CXCL4 is a member of the CXC chemokine family, which is mainly produced by platelets and known for its pleiotropic biological functions. CXCL4L1 exhibits a distinct subcellular localization has a distinct roles in inflammatory or homeostatic processes.3
