MSCs reduced MDSCs in apoE-/-Fas-/- mice. The ApoE^−/−Fas^−/− mice were injected with MSC or PBS via tail vein. Representative flow cytometry results and percentages of MDSCs of blood (A), spleen (B) and cervical lymph nodes (C) from ApoE^−/− Fas^−/− mice. The concentration of prostaglandin E metabolite (PGEM) in serum of ApoE^−/−Fas^−/− mice. AF, ApoE^−/− Fas^−/− mice, n = 9 mice/group, Data were based on three independent experiments. *p < 0.05, **p < 0.01, ***p < 0.001 using Student’s t-test
