In the present study we have identified a 72-kDa cell surface concanavalin A binding glycoprotein (cbg 72) involved in the chick embryo fibroblast (CEF) adhesion onto laminin (LM) substrate. The cbg 72 was shown to interact specifically with immobilized laminin and to be resistant to Triton X-100 extraction when CEF were plated on laminin substrate but not on fibronectin (FN) substrate. This behavior suggested that cbg 72 could interact with cytoskeletal elements during cell spreading onto LM. This assumption is also in good agreement with the partitioning of cbg 72 in Triton X-114. Isolated cbg 72 specifically inhibited CEF spreading onto LM after their initial attachment, whereas cbg 72 did not impair the spreading of CEF onto FN. These data provide a molecular explanation to the inhibition of CEF spreading onto LM observed in the presence of the lectin concanavalin A (P. Codogno, M.-A. Doyennette-Moyne, J. Botti, and M. Aubery, 1988, J. Cell Physiol. 136, 463-470). Moreover, these results provide evidence for the role of a novel LM binding glycoprotein during the adhesion of mesenchymal derived cells. The relationship between cbg 72 and other known cell surface LM binding sites or receptors is discussed.
