摘要：Despite the lack of direct evidence for cell multiplication, proliferation of smooth muscle cells in human atherosclerotic lesions has been assumed to play a central role in ontogeny of the plaque. We used antibodies to cell cycle-related proteins on tissue sections of human arteries and coronary atherosclerotic plaques. Specific cell types were identified by immunochemical reagents for smooth muscle, monocyte-macrophages, and other blood cells. Low rates of smooth muscle cell proliferation were observed. Macrophages were also observed with rates of proliferation comparable to that of the smooth muscle. Additional replicating cells could not be defined as belonging to specific cell types with the reagents used in this study. These findings imply that smooth muscle replication in advanced plaques is indolent and raise the possibility of a role for proliferating leukocytes.
