Recentin situstudies suggest the αvβ3integrin is a tumour progression marker in melanoma. We analyzed 5 human melanoma cell lines for their expression of the vitronectin binding αvβ3and αvβ5, integrins using flow cytometry. The role of these receptors in cell attachment, spreading and migration was investigated using attachment assays, video time lapse spreading and migration assays and with function blocking monoclonal antibodies. Cell lines derived from later stages of tumor progression exhibited high levels of αvβ3expression, whereas no similar correlation with αvβ5expression was identified. Cell attachment, spreading and migration response on vitronectin correlated well with the expression level of the αvβ3but not the αvβ5vitronectin receptor. Blocking of the αvβ3integrin resulted in a significant decrease in cell attachment, spreading and motility whereas the function blocking antibody against the αvβ5integrin only inhibited cell attachment in cell lines with the highest level of expression of this integrin. Taken together, our study indicates that the level of expression of the αvβ3and αvβ5integrins is heterogeneous in melanoma cell lines and that the αvβ5integrin, if present, may function only during the initial cell attachment whereas the αvβ3plays an important rôle in cell spreading and cell migration as well.
