the attachment of embryonic chick retinal cells to the 170,000-mol-wt protein also depends upon interactions between the protein and the heparan sulfate proteoglycan , since heparan sulfate in solution disrupts adhesion of chick neural retina cells to glass surfaces coated with the 170,000-mol-wt protein .
