T. Ota et al., CD44 PARTICIPATES IN TUMOR-CELL ADHESION TO ENDOTHELIAL-CELLS IN THE EXPERIMENTAL METASTATIC PROCESS IN B16BL6 MELANOMA-CELLS, Anticancer research, 15(4), 1995, pp. 1215-1219
There are several pieces of evidence suggesting a relationship between
CD44 expression and tumor metastasis, but the role of CD44 in the met
astatic processes is nuclear. We analysed the role of CD44 in the expe
rimental metastatic processes of B16BL6 melanoma cells using anti-CD44
monoclonal antibody (clone IM7). B16BL6 melanoma cells expressed CD44
and these cells treated with anti-CD44 monoclonal antibody increased
in the experimental metastatic ability, indicating that CD44 participa
tes in metastatic processes in B16BL6 cells. Fur thermore, the adhesiv
eness of B16BL6 cells to endothelial cells and the retention of these
cells in the lung increased by treatment with anti-CD44 monoclonal ant
ibody. These results suggested that the CD44-mediated adhesion of tumo
r cells to endothelial cells was involved in the experimental metastat
ic process of B 16BL6 cells.
