35S-labelled riboprobe in human endometrium to determine its temporal and spatial pattern of distribution throughout the menstrual cycle. The B? receptor mRNA was expressed in proliferative and secretory endometrium. In the early proliferative endometrium there were low levels of B2 receptor mRNA over both the glands and stromal cells. The signal increased in intensity and was localized over the glands with low levels of hybridization in the stroma in the late proliferative endometrium. In the early secretory endometrium B2 receptor mRNA was highly expressed in the endometrial glands. The strong hybridization signal persisted and in late secretory endometrium both glandular and stromal cells expressed B? receptor mRNA. The apparent increase in B2 receptor mRNA in the secretory endometrium suggests that bradykinin acting via Bj receptor may play a role in the increased vascular permeability and vasodilatation associated with implantation.
