We have used an in vitro adhesion assay to study the interaction of tumor cells with lymphatic endothelium, a dynamic event that leads to tumor metastasis in vivo.3H-thymidine-labeled human tumor cells from: one primary Ewing sarcoma, two established melanoma cell lines, two colon and two breast carcinomas (one established line and one primary culture of each) were added to 24-well culture dishes containing confluent monolayers of bovine lympathic endothelium. Radioactivity associated with either the cells in suspension or the attached cells was assessed and compared at frequent intervals up to 360 minuntes. Generally, tumor cell attachment increased as a function of time reaching a plateau between 180 and 360 minutes. The modular media system described here facilitates the primary and secondary culture (or co-culture) of a variety of normal and transformed cells. Primary cultures with a rounded morphology (one breast and one colon carcinoma) showed the lowest preferential attachment for lymphatic endothelium. All established cell lines and the primary Ewing sarcoma cell line displayed a more fibroblastic morphology and achieved the highest adhesion profiles. There was a correlation between the malignancy and attachment potential for the melanoma and breast carcinoma cell lines. Collectively, these data show that established tumor cell lines with fibroblastic-like morphology exhibit more rapid adhesion than primary tumor cell cultures with more rounded morphologies. While this property may reflect invitro selection and/or adaptation, it does correlate with the metastatic propensity for some human tumor cells.
