Ladsin is a large cell-adhesive protein with potent cell-scattering activity, which was recently identified in the culture of a malignant human gastric carcinoma cell line [Miyazaki, K. et al. (1993) Proc. Natl. Acad. Sci. USA 90, 11767-11771]. It is a heterotrimeric protein, containing a 140-kDa subunit similar or identical to the laminin B2t chain. Ladsin is similar to the keratinocyte-derived matrix proteins, "epiligrin" and "kalinin." In the present study, the cell-adhesion and cell-migration activities of ladsin were examined in comparison with those of three cell adhesion proteins, laminin, fibronectin, and vitronectin. Ladsin showed high cell-adhesion activity toward rat liver cell line BRL at concentrations 4-20-times lower than in the case of the other three proteins. In a monolayer culture, ladsin stimulated the migration of BRL cells about 2-times more strongly than the others, as compared at the minimal concentrations required for the maximal cell-adhesion activity. In Boyden chambers, ladsin stimulated both the chemotactic and chemokinetic migration of BRL cells. When the effect of anti-integrin antibodies on the adhesion of human fibrosarcoma cell line HT1080 was examined, the adhesion to ladsin was effectively inhibited by both the anti-integrin alpha 3 and beta 1 antibodies, but not the anti-integrin alpha 6 antibody, indicating that the primary receptor of ladsin is integrin alpha 3 beta 1. These results demonstrate that ladsin is a unique extracellular matrix component which may play a major role in cell migration.
