文摘

Magnesium (Mg) based metals possess unique features of biodegradation that can be used for different purposes. In this study, two tumor cells, MG63 and KB, were cultured directly on a pure Mg with and without MAO coating to evaluate their cytotoxic effects on the tumor cells. It was found that both MG63 cells and KB cells adhered better on the surface of the coated Mg samples than those on the pure Mg samples. However, the survivals of two kinds of tumor cells were obviously inhibited on both Mg samples with and without coating, compared with that on the pure titanium. In addition, the survival of MG63 cells was more susceptive to the Mg degradation compared with the KB cells. Thus, the application of such effect should take account of that the degradation of Mg based metal may result in different cytotoxic effect on different cells.
