The adhesive behaviour of a series of human melanoma cell lines, of varying metastatic potential, to basement membrane and stromal components was investigated in vitro. Experimental metastatic propensity was assessed from the number of pulmonary nodules formed after i.v. injection of cells into BALB/c nude mice. All cell lines showed similar kinetics of attachment when tested on plastic, type‐I collagen films, type‐I collagen hydrated gels, fibronectin, laminin type‐IV collagen substrates and bovine aortic endothelial monolayers. Fibro‐nectin‐coated plastic compared to plastic alone produced increased cell attachment and spreading to the same extent in all the cell lines. The melanoma lines attached preferentially to cryostat sections of lung compared to other organs reflecting the pattern of organ involvement of metastasis in vivo. However, no significant quantitative differences in attachment to lung sections were seen between melanoma variants of differing metastatic capacities. Cells labelled with [ 125 I]iodo‐deoxyuridine to determine their initial organ distribution following i.v. injection showed that tumour‐cell arrest was not significantly changed enough to explain the differing metastatic capacities. Thus it appears that adhesive properties of these melanoma cells are not correlated with their capacity to form metastases in vivo .
