Immunolocalization of PC5/6 protein in the rabbit uterus during pregnancy d0-6.5. Representative microphotographs are shown for pregnant d0-1 (A, B and C), d5 (D, E and F) and d6.5 (G, H and I). For each time point, panels depict an overview (A, D and G), endometrial mucosal folds (B, E and H) and basal glands (D, F, I). Arrowhead in G demonstrates increased basal glandular staining at the time of embryo attachment. Insets in A, D and G are negative controls. Scale bar = 25 μm.
