Popis: Thrombospondins (TSPs) are conserved, multi-domain, extracellular glycoproteins, that participate in many biological processes. TSP1 is present in low levels in the extracellular matrix (ECM) of healthy vessel walls but is up-regulated during neointima and plaque formation. TSP1 is responsible for inducing vascular smooth muscle cell (VSMC) proliferation and migration upon vascular injury or during atherosclerosis. We have examined the organisation of elastic fibril layers in the aortae of 10 to 12-week old wild-type and Thbs1 -/- female and male mice. The total width of elastic layers was measured from medial cross sections of the ascending arch and thoracic aorta. 1055 measurements were made from Thbs1 -/- and 671 from wild-type sections. The total width of layers is increased in Thbs1 -/- mice (p
