FIG. 2.

Immunohistochemical MMP2 expression in decidual cells from preterm specimens. Matrix metalloproteinase 2 immunoreactivity (brown) is evident in preterm control (A; n = 11) and preeclamptic (C; n = 11) decidual tissues. Decidual cells are stained for vimentin (red) in the decidua of women with preterm control (B) and preeclamptic (D) deliveries. E) Negative control. Original magnification ×40. Inset box in B demonstrates interstitial trophoblast cells stained for cytokeratin (red). HSCORE values for MMP2 expression (F) are compared between decidual cells of preterm controls versus those from preeclamptic specimens, as well as between interstitial trophoblast cells of controls versus preeclamptic specimens (both not significant).
