The effect of etretinate on proliferation and biosynthesiso f collagensa nd glycosaminoglycans(G AGS) were
\ninvestigatedu sing human dermal fibroblasts in a novel three-dimensionacl ulture supplementedw ith L-ascorbica cid
\n2-phosphate. Fibroblasts from two young and two elderly individuals were studied at different concentrations of
\netretinate, 0.25, 1. O and 2.5 pg/ml. Collagens( hydroxyproline) and GAGS (disaccharideu nits) extracted from the cell
\nlayer were analyzed and quantified biochemically by high-performance liquid chromatography (HPLC). Etretinate
\nshowed no significant effect on fibroblast proliferation either in the monolayer or the three-dimensionacl ulture.
