The enhanced metastatic capacity of an in vivo selected Lewis lung tumor line (LLT-HH) was correlated with changes in cell-associated glycosaminoglycans (GAG) using ultrastructural cytochemistry, flow cytometry and biochemistry. The increase in highly sulphated GAG content on the cell membrane of LLT-HH cells compared to the parent LLT cells was demonstrated cytochemically. Using in vitro [3H]glucosamine labelling of GAG components it was shown that the LLT-HH cells were characterized by a high production of heparan sulphate while the parent LLT line had a high hyaluronic acid-chondroitin sulphate production. The high metastatic phenotype is accompanied by an altered production of cell-associated GAGs.
