IL-11 and IL-11Rα immunolocalisation at primate implantation sites supports a role for IL-11 in placentation and fetal development

Table 1 IL-11 immunostaining in cynomolgus and rhesus monkey implantation sites, and human first trimester decidua and placenta.

Relative staining intensities are represented as: – (no staining), + (low), ++ (moderate) and +++ (high). Trophoblast cellular compartments include: Chorionic villi (villi), villous cytotrophoblast (cyto), villous syncytiotrophoblast (syncytio), villous stromal mesenchyme (mesenchyme), cytotrophoblast shell (shell), cytotrophoblast invading spiral artery (cyto-invading artery). Maternal cellular compartments include: decidua, vascular smooth muscle cells (VSM), endothelial cells, glands, perivascular cells and epithelial plaque.
