[Electron microscopic and cytochemical data on the interaction between endothelial cells and thrombocytes]
1Anatomical Institute, Albert-Ludwigs-University, Freiburg FRG.
The data obtained demonstrate that besides the known adhesion and aggregation of thrombocytes when intima is injured and endothelium is desquamated, there are some other mechanisms. Thus, the thrombocytic aggregation is possible in the area of intracellular accumulation of lipid inclusions and calcium depositions in the uninjured endothelial cells. A suggestion is made on a trigger role of the external membrane of the endotheliocyte in this process.
