A cell surface chondroitin sulfate proteoglycan associated with human melanomas and defined by mAb's F24.47 and 48.7 has been characterized biochemically and localized by indirect immunogold electron microscopy. These antibodies recognize distinct epitopes on the intact proteoglycan. In addition, mAb 48.7 also recognizes an epitope on a 250,000-D(More)
Cultured fibroblasts form focal contacts (FCs) associated with actin microfilament bundles (MFBs) during attachment and spreading on serum- or fibronectin (FN)-coated substrates. To determine if the minimum cellular adhesion receptor recognition signal Arg-Gly-Asp-Ser (RGDS) is sufficient to promote FC and MFB formation, rat (NRK), hamster (Nil 8), and(More)
