The effect of gestation on FAAH immunoreactivity. FAAH immunostaining is present throughout the first trimester in both the trophoblast (upper panels) and decidua (lower panels). In the trophoblast, the majority of the staining was confined to the cytotrophoblast and syncytiotrophoblast layers, although significant immunoreactivity was observed in the mesenchymal core. The intensity of FAAH immunoreactivity throughout the trophoblast diminished in weeks 11 and 12 of gestation. Intense immunoreactivity was observed in the decidualised stromal fibroblasts and decaying endometrial glands. The intensity of decidual cell staining increased and reached a peak around week 10 and was diminished by 12. Images were taken at 100× magnification. Bar = 50 μm.
