Figure 1. PPARγ and NF-κB staining were found in the membrane and cytoplasm of placental trophoblast cell.

×400 (A–C) PPARγ protein expressed in the placenta of control patients, mild ICP patients and severe ICP patients. (D–F) NF-κB protein expressed in the placenta of control patients mild ICP patients and severe ICP patients. PPARγ and NF-κB proteins expression were significantly different in control group and ICP groups.
