[The effect of alkyl-lysophospholipids and membrane potentials, proliferation and migration of isolated calf aorta endothelial cells].

Cancerostatical active synthetic alkyl-lysophospholipids were examined with regard to their effects on membrane potential, proliferation and migration of isolated endothelial cells. In sublytic concentrations all alkyl-lysophospholipids tested caused a hyperpolarization of the membrane of endothelial cells. The effect of alkyl-lysophospholipids on proliferation of endothelial cells was dependent on the serum supplement. The migration of endothelial cells was strongly inhibited by 1-O-octadecyl-2-O-methyl-glycero-phosphocholine. Possible mechanisms of action are discussed.
