Platelets form thrombi at vascular injuries thereby preventing excessive bleeding. Platelets are considered to be immotile, firmly attaching to subendothelial matrix or plasma proteins. By single cell tracking in multicolor platelet reporter mice, we demonstrate autonomous locomotion of activated platelets within their physiological environment. Governed by the local adhesiveness of the microenvironment, platelet migration facilitates the redistribution of individual platelets towards regions of higher adhesiveness, thereby reorganizing thrombi in vivo.
