Mesenchymal stem cells from the decidua basalis (DB-MSCs) show strong immunosuppressive capacity. a The significant difference between groups A and B indicated that phytohemagglutinin (PHA) stimulated peripheral blood mononuclear cell (PBMC) proliferation (**P < 0.01, n = 10). There was no difference between groups C and D or between groups F and G (P > 0.05), which indicated that PHA had little effect on the proliferation of MSCs. DB-MSCs showed stronger immunosuppression properties than did mesenchymal stem cells from Wharton's jelly (WJ-MSCs) (*P < 0.05). b The IFN-γlevel in the supernatantwas lower in the DB-MSC group than in the WJ-MSC group (*P < 0.05)
