Figure 1: (A) mRNA gene expression of immunomodulatory genes of BM-MSC and ASC with or without IFNγ stimulation, n=5 for BM-MSC and n=5 for ASC. Ratio gene/GAPDH x1000 is shown. Means (SD) are depicted, *represents P<0.05. (B) Effect of IFNγ stimulation on IDO activity in BM-MSC and ASC determined by measurement of L-kynurenine in medium conditioned with unstimulated or IFNγ stimulated BM-MSC and ASC, n=4 for BM-MSC and n=4 for ASC, means (SD) are depicted, *represents P<0.05.
