The synthesis of proteoglycans in fat‐storing cells of rat liver
Stephan Schäfer, Ottwin Zerbe, Axel M. Gressner – 1 July 1987 – Fat‐storing cells (perisinusoidal stellate cells) were isolated by enzymatic digestion of rat liver and purified by a single‐step Nycodenz ® gradient to yield 11.4·106 cells per liver, with a purity of 74% and a viability of 76%. Monolayer cultures of fat‐storing cells incorporated both [35S]sulfate and [3H]glucosamine into glycosaminoglycans; the rate of incorporation increased with culture time (3‐fold between the third and eighth days in culture). About 80% of newly formed glycosaminoglycans were secreted into the medium.
