In this review, the technique of electron tomography is shortly summarized. Alignment procedures on the electron microscope are described. New techniques such as the focused ion beam tomography, the block face scanning tomography and the array tomography are mentioned. Application of these methods for vascular research, concerning endothelium-specific Weibel-Palade bodies in cell cultures from human umbilical vein endothelial cells and endothelial progenitor cells as well as about cellular communications between the endothelium and the subendothelium are referred. Platelets are important players in the interaction with the endothelium in thrombosis and hemostasis after transfusion, therefore electron tomographic investigations of platelet organelles as well as platelet microparticles are mentioned. Illustrations from our own investigations are added.
