• unlike transgenic mice wild-type for Ptger2, 12 week old virgin females do not display precocious mammary gland development
• in contrast to transgenic mice wild-type for Ptger2, few multiparous females develop mammary gland hyperplasia

neoplasm
• in some cases mammary gland adenomatous carcinomas metastasize to peripheral lymph nodes
• adenomatous carcinomas of the mammary epithelial cells contribute the hyperplastic alveolar nodules that are seen with high frequency in multiparous females

endocrine/exocrine glands
• delay in the early stages of involution
• however, by 7 days post weaning mammary glands are regressed
• adenomatous carcinomas of the mammary epithelial cells contribute the hyperplastic alveolar nodules that are seen with high frequency in multiparous females
• hyperplastic alveolar nodules are seen with high frequency in multiparous females
• alveolar hyperplasia, squamous metaplasia, and adenomatous carcinomas of the mammary epithelial cells contribute to these lesions
