Expression of a cell surface antigen with potential Ca2+-sensor/receptor function in rat placenta and uterus.
The reactivities of monoclonal anti-parathyroid antibodies identifying a cell surface 'calcium sensing' mechanism were investigated in the placenta and uterus of the pregnant rat. The rat placenta showed positively stained cells at the end of pregnancy. Staining was confined exclusively to the columnar epithelial cells lining the sinuses of Duval. In the uterus, positive staining of the epithelium lining the uterine lumen was obtained exclusively prior to and during implantation.
