Innate immune responses were reduced by hAMSCs in APAP-Exposed Livers. Inflammatory gene (A) and cytokine (B) expression were measured from liver tissue or serum by quantitative RT-PCR and ELISA. *, P<0.05. Data are mean ± SEM from 5 independent experiments. *, P<0.05, n=6 for each group. hAMSC, human amniotic mesenchymal stromal cell; APAP, Acetaminophen; RT-PCR, reverse transcription-polymerase chain reaction.
