Control of B16 melanoma cells differentiation and proliferation by CuSO4 and vitamin C.
The effects exerted by CuSO4, in the presence or absence of vitamin C, on melanogenesis and proliferation in mouse B16 melanoma cells in culture were analysed either in serum-free (MEM-N2) or in serum-supplemented media. The stimulation or the inhibition of these cellular parameters can be induced, depending on the metal concentration, the presence or absence of vitamin C, the composition of the culture medium and on the type of culture (subconfluent or clonal). Vitamin C toxicity for B16 cells was generally increased in serum-free medium, in clonal cultures, or in the presence of CuSO4.
