furthermore , heparan sulfate and the chondroitin sulfates , which were enriched in the substratum material and in the cell pellet of exponential cultures , showed a relative shift to the cell surface-associated compartment ( releasable by mild trypsinization after egta-mediated cell detachment ) and to the compartment loosely associated with the pericellular matrix ( i.e. , released into the supernatant during detachment of the monolayers in the presence of egta ) .
