MSC immunosuppressive effect on lymphocyte proliferation. Data show the percentages of residual proliferative capacity of stimulated lymphocytes in the absence (CTRL) or in the presence of BM-MSCs, UCT-MSCs and AT-MSCs at ratio 1:4 and 1:8 (MSCs:PBMCs), either in cell-cell contact or in transwell system, evaluated at 72 h, 96 h and 120 h. (F = 29.025 and p = 0.000 at ANOVA and ^* p = 0.000 for BM vs AT, ^* p = 0.001 for BM vs UCT, ^# p = 0.029 for AT vs UCT at Scheffe test for 1:4 ratio in contact cultures; F = 53.301 and p = 0.000 at ANOVA and °p = 0.000 for BM vs AT, °p = 0.001 for BM vs UCT, p = 0.237 for AT vs UCT at Scheffe test for 1:4 ratio for transwell cultures; F = 6.57 and p = 0.008 at ANOVA and p = 0.152 for BM vs AT, ^§ p = 0.009 for BM vs UCT, p = 0.328 for AT vs UCT at Scheffe test for 1:8 ratio in contact cultures; F = 2.86 and p = 0.088 at ANOVA and p = 0.151 for BM vs AT, p = 0.152 for BM vs UCT, p = 0.981 for AT vs UCT at Scheffe test for 1:8 ratio in transwell cultures).
