endocrine/exocrine glands

abnormal milk ejection ( J:92770 )

♀ • 10 out of 12 dams were unable to secrete milk, while the remaining 2 could secrete only small amounts of milk

abnormal branching of the mammary ductal tree ( J:92770 )

♀ • the number of tertiary branches is severely decreased, the lobular units are absent, and at parturition the alveolar compartment is missing

♀ • treatment with estrogen and progesterone induces very little side branching in mammary epithelia unlike in wild-type females
