Human chondrosarcoma of low-grade malignancy was cultured in the presence of 35S-sulphate and 3H-glucosamine. The glycosaminoglycans isolated were fractionated on Ecteola cellulose and electrophoresed on cellulose acetate membranes before and after treatment with chondroitinase AC or Streptomyces hyaluronidase. The results demonstrated the in vitro synthesis of hyaluronate, chondroitin sulphate and keratan sulphate. The presence of keratan sulphate of large average chain length (congruent to 15 monosaccharides) supports the contention that chain length of keratan sulphate is inversely proportional to the degree of malignancy.
