Cytokine expression by fetal and maternal P-MSCs in response to IFN-γ and Poly (I:C) stimulations. Equal numbers of cells from fetal and maternal P-MSCs were seeded and stimulated with IFN-γ (A) and Poly (I:C) (B). Cytokine levels in cell culture supernatants were quantified by ELISA and normalized by cell numbers at the end of the study. n = 3. *: P <0.05, **: P <0.01. IFN-γ, interferon gamma; P-MSCs, placental mesenchymal stem cells.
