Analysis of heparan-sulphate chains and oligosaccharides from proliferating and quiescent fibroblasts. A proposed model for endoheparanase activity
Human skin fibroblasts in different growth states were incubated with [3H]glucosamine and/or Na(2)35SO4 and extracted with Triton X-100 for various periods of time. Free heparan-sulphate oligosaccharides and protein-bound heparan-sulphate chains were separated by chromatography on octyl-Sepharose and analyzed. A pool of endogenously produced oligosaccharides, present in the cultured cells and isol
