For the successful establishment of secondary tumours, blood-borne metastatic tumour cells must adhere and spread on the vascular endothelium before they can migrate through it to form secondary growths in the tissue beneath. In this study an in vitro assay was developed to study the behavourial interactions between B16F10 cells and Bovine aortic endothelial cells. It was hypothesized that molecules synthesized by the endothelial cells may be involved in the mediation of the adhesion, spreading and migration events and hence that such molecules may possibly be involved in the process of haematogenic metastasis. Endothelial derived extracts were obtained from the cell surface and from conditioned medium. The extracts were tested for their adhesion promoting abilities in a quick dot blot adhesion assay. To verify that these molecules promoted adhesion, antibodies were raised against the extracts. Partial characterisation of the molecules was achieved using SDS-PAGE and immunoprobing. The extracts were also tested for their spreading and migration promoting properties. An attempt was made to block the adhesion, spreading and migration events using antibodies directed against components of the extracts. Clearly, if endothelial-derived molecules are involved in metastasis, then preventing the mediation of adhesion, spreading and migration may ultimately have relevance in the clinical situation.
