摘要:: To study the biology of the endothelium under conditions that mimic the architecture of the vessel wall, endothelial cells were grown on a collagen lattice containing a multilayer of smooth muscle cells. Light and electron microscopy of such cultures revealed a confluent monolayer of flattened endothelial cells. In co-culture, endothelial cells tend to elongate, whereas in the absence of smooth muscle cells, the endothelial cells show the polygonal morphology typical for cultures of endothelial cells grown on polystyrene substrates. As conditioned culture media of endothelial cells contain substances that may both promote or inhibit the growth of smooth muscle cells, the availability of this vessel wall model prompted us to examine to what extent endothelial cells regulate the proliferation of smooth muscle cells when these cells are maintained in co-culture. Here we show that endothelial cells suppress the proliferation of co-existing smooth muscle cells. This finding suggests that under physiological conditions the balance of the action of growth-promoting and growth-inhibiting substances produced by endothelial cells is in favour of the latter.
