Figure 5. The placenta releases sST2.

Figure 5

sST2 (A) and IL-33 (B) were detected by ELISA in maternal side perfusate from an ex vivo of placental perfusion model. Normal (n = 8) and pre-eclampsia (PE) (n = 5) placentas were perfused. sST2 could be identified in media from all of the normal and pre-eclampsia placental perfusions, IL-33 could be identified in one sample from a normal pregnancy. Bars represent median values. C) Placental explants release sST2, secretion was increased by treatment with TNFα and IL-1β (100 ng/ml) and hypoxia-reperfusion injury, and was decreased under hypoxic conditions (n = 3).
