these data indicate that ( a ) 3t3 cell surface heparan sulfate proteoglycan is not involved in growth control but may be involved in cell spreading , ( b ) the use of chlorate should be a valuable method for the study of the biosynthesis and structure/function relationships of sulfated glycosaminoglycans , and ( c ) the temporal sequence of the heparan sulfate chain modification reactions predicted from results of studies with cell-free extracts also operates in the cell .
