Mammary glands of lactating mice, either intact or ovariectomized, do not contain detectable amounts of progesterone receptors and this lack of receptors persists also in tissues of animals treated with oestradiol. In contrast with lactators, mammary glands of virgin mice contain progesterone receptors whose amounts are augmented by oestradiol administration.
处于哺乳期的小鼠,无论乳腺完整与否或是否已切除卵巢,其乳腺中均未检测到孕酮受体,并且在用雌二醇处理的动物组织中也持续缺乏这种受体。与哺乳期小鼠相反,未生育小鼠的乳腺含有孕酮受体,其含量在用雌二醇处理后会增加。
