Figure 3. IL-33 expression in pathologic pregnancies.

Figure 3

(A) IL-33 is expressed in the nuclei of endothelial cells of decidual blood vessels in patients with preterm labor. IL-33 is not expressed in the mesodermal layer of the amnion. x200 magnification. (B) IL-33 is expressed in the nuclei of macrophages in the chorioamniotic membranes of patients with preterm labor and acute chorioamnionitis. x200 magnification. (C) IL-33 is not expressed in macrophages in the chorioamnionic membranes of patients with preterm labor and chronic chorioamnionitis. x200 magnification. Arrowheads are endothelial cells and thick arrows are macrophages for all. AE = amnion epithelium; AM = amnion mesoderm; CM = chorionic mesoderm; CT = chorionic trophoblast layer; DP = decidua parietalis.
