  • Title: The effect of centrifugal force on glycosaminoglycan production by aortic smooth muscle cells in culture.
    Author: Merrilees MJ, Merrilees MA, Birnbaum PS, Scott PJ, Flint MH.
    Journal: Atherosclerosis; 1977 Jul; 27(3):259-64. PubMed ID: 901622.
    Abstract:
    Cultured smooth muscle cells from pig aorta subjected to centrifugation (48 h at 45 g over a 72-h period) increased their production of glycosaminoglycans by approximately 50%. The sulphated components, heparan sulphate, dermatan sulphate and chondroitin sulphate, showed a relatively greater increase than hyaluronic acid (66-34%). The results are consistent with the hypothesis that mechanical stress, such as hypertension, leads to increased accumulation of glycosaminoglycans in the aortic wall and that secondary trapping of lipoproteins by sulphated glycosaminoglycans produces atherosclerotic plaques.
