short-term ( several days ) or long-term ( several weeks and months ) treatment of cultured human diploid fibroblasts ( wi-38 ; phase ii ) with heparin at 20 -- 500 micrograms/ml inhibited cell proliferation and stimulated glycosaminoglycan synthesis ( as measured by the incorporation rates of [ 35s ] sulfate and [ 14c ] glucosamine into cellular and medium glycosaminoglycans ) .
