Comparative analysis of immunocritical melanoma markers in the mouse melanoma cell lines B16, K1735 and S91-M3.
The mouse melanoma cell lines B16, K1735 and Cloudman S91-M3 (and various sublines) are frequently used as melanoma models. Extensive comparative data of their immunological features are not available. In order to define the immunological profiles of these cell lines, relevant tumour markers were studied. S91-M3 melanoma cells constitutively expressed high levels of major histocompatibility complex (MHC) I, in contrast to K1735-M2 and B16-F1 cells. MHC II expression was restricted to B16-F1 cells following interferon-gamma treatment. Tyrosinase, tyrosinase-related protein-2 and gp100 were detected in B16-F1 and S91-M3 cells, but not in K1735-M2 cells. Constitutive surface expression and secretion of intercellular adhesion molecule-1 was found on S91-M3 cells. No substantial secretion of interleukin-10 could be detected. In contrast, low levels of latent transforming growth factor-beta were found in the cell supernatants of B16-F1 and K1735-M2 cells. The expression pattern of Fas, FasL and FLICE inhibitory protein was comparable in all three cell lines. Thus our findings indicate that each cell line presents a characteristic immunological profile, confirming that B16-F1 is an appropriate murine tumour model for tumours with low levels of MHC I but expressing melanoma-associated antigens. S91-M3 represents a complementary, more immunogenic model. In contrast, K1735-M2 does not seem to be an appropriate model for melanoma.
