AMMSCs in PL showed superior immunosuppression effects with UCMSCs. When primed by IFN-γ and/or TNF-α induction, PGE2 (a) and TGF-β1 (b) expression were analyzed. IDO activity (c) was evaluated by kynurenine levels. (d) UCMSCs suppressed allogeneic lymphocyte proliferation. Bars represented means ± SD, n = 5; *P < 0.05
