摘要:: Dimethylsulfoxide-soluble particles (DSP) from cigarette smoke and ultraviolet light caused a low degree (cell death less than 30%) and high degree (cell death 60-90%) injury to bovine arterial endothelial cells and smooth muscle cells in culture. Conditioned medium from low degree injured endothelial cells and smooth muscle cells generally inhibited DNA synthesis in new smooth muscle cells or endothelial cells while high degree injury increased DNA synthesis in new cells. Specifically, the growth stimulating activity from endothelial cells was decreased after low degree injury but increased after high degree. UV light released more growth stimulating substances from smooth muscle cells after both low and high degree injury. The release of growth inhibiting substances was dependent on both cell kind and degree of injury. In co-culture low and high degree DSP injury to endothelial cells inhibited smooth muscle cell proliferation, which was in contrast to the effect of conditioned medium from high degree injured endothelial cells. Conditioned medium from endothelial cells treated with LDL and glucose inhibited DNA synthesis in smooth muscle cells. It is concluded that injury to endothelial cells or smooth muscle cells will modify the release of growth inhibiting and growth stimulating activity and that this release will depend on cell kind as well as degree and kind of the injurious stimulus.
