Figure 1From: Estrogen and progesterone receptors have distinct roles in the establishment of the hyperplastic phenotype in PR-A transgenic miceWhole mounts of mammary glands of adult mice carrying additional A form of PR. Whole mounts of mammary glands derived from (a) intact PR-A transgenic mice, (b) ovariectomized PR-A transgenic mice, (c) ovariectomized PR-A transgenic mice treated with estradiol 1 μg for 5 days, (d) ovariectomized PR-A transgenic mice treated with estradiol 1 μg and progesterone 1 mg for 5 days, (e) intact PR-A transgenic mice treated with ICI 182,780 for 4 days, (f) intact PR-A transgenic mice treated with ZK98,299 for 4 days, and (g) intact PR-A transgenic mice treated with RU486 for 4 days.Back to article page
