The purpose of this study was to determine whether the expression of melanoma cell adhesion molecule (MCAM/CD146), like most other endothelial adhesion molecules, is reduced in the pregnancy disorder pre-eclampsia, and whether it is associated with the invasiveness of trophoblast. We used immunohistochemical approaches and analyzed 42 placentas from control and pre-eclamptic patients using an anti-CD146 monoclonal antibody. Our data show that in normal placentas, CD146 staining was specifically detected in intermediate trophoblasts that are most invasive and migratory, but not detected in noninvasive cytotrophoblasts or syncytiotrophoblasts. However in pre-eclampsia, CD146 was no longer present in the intermediate trophoblasts, although it was detectable in the blood vessels. At the same time, we tested CD31/PECAM-1, another endothelial adhesion molecule, and found its negative staining for all kinds of trophoblasts in both normal and pre-eclamptic placentas. The different staining patterns of CD146 in the normal and pre-eclamptic placentas provide the first evidence that in pre-eclampsia, intermediate trophoblasts fail to express CD146, implicating that CD146 plays an important role in trophoblast invasion.
