Figure 5From: Steroid hormone regulation of EMP2 expression and localization in the endometriumProgesterone induces surface expression of EMP2 in mouse endometrium in vivo. Mice were injected with progesterone or sesame oil (control) daily for up to 5 days. Tissue was harvested at days 1, 2, and 4 of treatment or 3 days following completion of treatment, processed for immunohistochemistry, and then stained for EMP2 expression (A-D) or a vehicle control (E). (A) 24 hours of progesterone treatment; (B) 48 hours of treatment; (C) 4 days of treatment; (D) 3 days following treatment; (E) representative control treatment at 4 days. Magnification: (left) 100×; (right) 400×. The experiment was repeated at least 3 times with similar results; representative images are shown.Back to article page
