IDO activity of tissue specific hMSCs after pre-conditioning with different Dex concentration at 24 h and 48 h; a The bar graph represents that BM-MSCs after preconditioning with 3000 ng/ml at 48 h shows significant upregulation among the other preconditioning combinations. b and c The bar graph represents that AD-MSCs and DP-MSCs shows similar response to Dex preconditioning compared to untreated hMSCs. d The bar graph represents that UC-MSCs after preconditioning with 3000 ng/ml for 24 h shows significant upregulation. Data from three donors in duplicates and shown as mean ± SD; ***p < 0.001, **p < 0.01, *p < 0.05
