Implantation site in complete molar pregnancy: a study of immunologically competent cells with monoclonal antibodies.
The nature and intensity of inflammatory cellular infiltrate in the implantation sites of 10 complete molar pregnancies were evaluated by immunohistochemical staining of frozen tissue sections with monoclonal antibodies. As compared to the implantation site in normal pregnancy, there was an increase in the number of infiltrating inflammatory cells in the molar implantation site. Most of the inflammatory cells were T cells with predominance of T4+ (Leu-3a+) cells over T8+ cells. Inflammatory cells were not detected in the molar vesicles. The possible implications of these findings in molar pregnancy are discussed.
