Immunolocalization of PC5/6 protein in the rabbit uterus on pregnant d7-10 and pseudo-pregnant d8. Representative microphotographs are shown for pregnant uterus on d7 (A, B and C), d8 (D, E and F) and d10 (G, H and I), and pseudo-pregnant uterus on d8 (J, K and L). For pregnant uterus, panels depict an overview (A, D, G), attachment region (B, E and H) and non-attachment region (D, F and I) for each time point. Arrows in A, D and G highlight the embryonic tissues. Arrowheads in H show decidual cells; the insert shows a higher magnification. For pseudo-pregnant uterus, an overview (J), mucosal folds (K) and deep basal glands (I) are shown. Inserts in A, D, G and J are negative controls. Scale bar = 25 μm.
