title: [The activated modified smooth muscle cell: morphology, metabolism, distribution and transitory forms].
abstract: On human as well as on animal vascular material a characteristic distribution of activated smooth muscle cells is observed which is characteristic for the course of a lesion. In early stages these cells are above all found below the tunica elastica as well as in the marginal parts of the plaques, whereas later on the distribution is increasingly balanced. These cells are metabolically active and also show a higher division rate. The morphological characteristics of the activated smooth muscle cells are a reference to the metabolic and synthetic activity of the cells. Independent on this a characteristic content of activated smooth muscle cells is revealed during ageing. It is still unclarified in as far prognostic conclusions may be derived from the distribution of this cell form on the human vascular material.
