endocrine/exocrine glands
N
• normal lactation
• more proliferative at lactation day 1
• increased terminal end bud number
• enhanced ductal extension during pubertal mammary development
• prolific alveologenesis during mid pregnancy at day 14.5 post conception and at lactation day 1

homeostasis/metabolism
• 2x increase in lung metastatic nodules in DMBA-induced mammary tumor bearing mice
• invasive fronts of pre-neoplastic mammary lesions create microscopic projections of epithelial cells into surrounding stroma after induction with DMBA
• normal latency to mammary tumor growth after induction with DMBA
• normal mammary tumor growth rate after induction with DMBA
