From: Sensitization of interferon-γ induced apoptosis in human osteosarcoma cells by extracellular S100A4
Addition of recombinant S100A4 sensitizes OHS and II-11b cells to IFN-γ-induced apoptosis. Cell viability was measured in OHS and II-11b cells after addition of the indicated concentrations of recombinant S100A4 to the cell culture medium with or without 100 u/ml IFN-γ. All values are given as a percentage of viable cells relative to untreated control cells. The results are presented as mean values ± S.D. of at least three independent experiments performed in triplicate. *, p < 0.0001 and **, p < 0.05 as compared to untreated control cells.
