Localization of three subtypes of Fc gamma receptors in human placenta by immunohistochemical analysis.

abstract：:Amnion is the innermost layer of the fetal membrane and has been suggested to regulate the volume of amniotic fluid via the amniotic epithelium. The transepithelial pathway is generally restricted by tight junctions (TJs). Thus far, human amniotic TJs have not been identified. In this study, we determined whether the ...
