Abstract

- The hypothesis that cells of the arterial wall might modify the consequences of arterial injury was tested. Bovine aortic endothelial cells (EC) or smooth muscle cells (SMC) were exposed to the two toxic stimuli 3,4-benzo(a)pyrene (BP) and dimethylsulfoxide-soluble particulate matter from cigarette smoke (DSP) or factors released from platelets. The modification of the injury caused by these substances on arterial cells was studied by using a conditioned medium from arterial cells or an EC-SMC co-culture model. Direct addition of BP or DSP to the EC or SMC cultures induced toxic effects on the cells. DSP caused a decreased release of prostacyclin by EC. Conditioned medium from EC and SMC modified these toxic effects, which resulted in a reduced cell death and a further decreased cell proliferation, while conditioned medium from SMC increased the release of prostacyclin by EC injured by DSP. In EC-SMC co-culture the same modifications were obtained. The modification of cell injury was not linked to cell proliferation but instead the results suggested that the effects were mediated by multiple substances released from arterial cells. It is concluded that interactions between different cells in the arterial wall, in the non-injured as well as in the injured state, could be modified by endogeneous substances. This might be of relevance for atherogenesis.
