human neuroblastoma cells ( platt and la-n1 ) have previously been shown to adhere and extend neurites on tissue-culture substrata coated with a 120k chymotryptic cell-binding fragment ( cbf ) of plasma fibronectin ( pfn ) , a fragment which lacks heparan sulfate- and collagen-binding activities , and to adhere to -- but not extend neurites on -- substrata coated with the heparan sulfate ( hs ) -binding protein , platelet factor-4 ( pf4 ) ( tobey et al. , exp cell res 158 ( 1985 ) 395 [ 3 ] ) .
