Ectoplacental cone induces resistance to apoptosis in high doses of interferon (IFN)‐γ‐treated decidual cells. Am J Reprod Immunol 2012; 67: 73–83 Problem  In this study, we explored the relationship between decidual cells (DC) and interferon (IFN)‐γ, in the presence or absence of ectoplacental cone (EC) using a coculture system. Method of study  Decidual cells and EC were isolated from pregnant mice on gestation day 7.5. DCs were cultured for 48 hr and then treated with fresh EC. After characterization, they were treated with IFN‐γ, and cell death was evaluated. Results  Interferon‐γ drastically increased decidual apoptosis, which was partially reverted by the addition of EC to the IFN‐γ‐treated decidual culture. Moreover, the addition of EC to non‐treated DC cultures was also capable of attenuating death rates. Conclusion  Resistance to apoptosis may be induced in DC by the EC. This suggests that EC may participate in the inhibition of IFN‐γ‐dependent apoptosis and, therefore, play important role for DC survival in a cytokine‐enriched placental environment.
