Materials and Methods: A cell line (CRBM-1990) was isolated from a renal cell carcinoma bone metastasis and compared with the ACHN and Caki-1 established lines. The expression of osteolytic cytokine and angiogenetic growth factors mRNAs, as well as the effect on migration and proliferation of a bovine bone cell line (BBE) were determined. Results: There were no significant differences between the three lines in IL-6, TGF-β, VEGF-A, VEGF-B, VEGF-C and FGF-2 mRNAs expression. VEGF-D, PlGF, or RANK-L-specific mRNA were not expressed. CRBM-1990-, Caki-1- and ACHN-conditioned media significantly stimulated the migration and proliferation of BBE. Conclusion: CRBM-1990 expressed IL-6-specific mRNA, but not RANK-L, expressed angiogenetic growth factors and induced migration and proliferation of bone endothelial cells at a non-significantly different level when compared with Caki-1 and ACHN.
