The expression of Cav1 and Rxfp2 in mouse uterus. A, Immunohistochemical localization of CAV1 in wild-type uterus and an absence of staining in Cav1−/− uterus. Females (1 yr old) were used. Strong signal was detected in endothelial cells of the blood vessels and myometrium. Note an absence of staining in glandular endometrial epithelium. B, The β-galactosidase staining showing the Rxfp2-promoter-dependent expression of iCre recombinase in Rxfp2-iCre, R26R transgenic mice (left). No staining was detected in uterus of R26R controls (right). The most prominent blue staining is located in endometrial glandular epithelial cells and luminal epithelium. Two month old females were used. Magnification bar, 100 μm.
