Localization of endometrial enzymes involved in polyamine synthesis. AZIN2 and ODC1 proteins localized to uterine luminal epithelia (LE), superficial glandular epithelia (sGE), and stromal cells in both P4- and CO-treated ewes on day 9 and 12 of pregnancy (a and c). Intensity of AZIN2 staining in the LE was not associated with day or treatment (b). Intensity of ODC1 staining in the LE was decreased in endometria from P4-treated ewes compared to CO-treated ewes (d). Scale bar represents 100 μm. Only endometria from ewes which were considered pregnant with normally developed conceptuses were utilized for these analyses
