|
• mammary glands in 4-, 6-, and 12-week old females weigh 18-23% less than in control female littermates
|
|
|
• by fourth to sixth weeks of age, ductal system has 30-50% less extension with reduced numbers of terminal end buds than in control females
• at maturity (8, 16 and 20 weeks) mammary glands are filled with large bloated ducts terminating with bloated ends; glands have fewer secondary and tertiary ductal branches compared to controls; during pregnancy, retarded ductal branches are partially restored, but mutant mammary glands still have less milk-producing alveoli than control glands
|
|
|
• retardation of mammary gland development may affect capacity of females to provide milk for their offspring
