UC-MSCs combined with decitabine induced M2 macrophage polarization and activation of the IL-4R/STAT6/PPARγ pathway. a Immunoblotting analysis of macrophages from the Con, LPS + IFN-γ, MSC, DAC, and MSC + DAC groups. b–e Relative protein levels of IL-4R, p-STAT6, p-STAT3, and PPARγ are shown. Images of a are representative of three independent experiments. *P < 0.05; **P < 0.01
