phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• no mice are recovered at birth when exposed to doxycycline throughout pregnancy

reproductive system
• mice treated with doxycycline from birth exhibit defective lobuloalveolar differentiation during mid- and late pregnancy that persists in parturition compared with wild-type mice
• however, alveolar lumina are filled with milk

integument
• of terminal end bud in mice treated with doxycycline from birth
• at 4 and 6 weeks, mice treated with doxycycline from birth exhibit delayed mammary gland outgrowth compared with wild-type mice
• at 4 weeks, mice treated with doxycycline from birth exhibit distal ends without terminal end bud appearance unlike in wild-type mice
• however, outgrowth at 9 weeks and mammary epithelium architecture are normal
• mice treated with doxycycline from birth exhibit defective lobuloalveolar differentiation during mid- and late pregnancy that persists in parturition compared with wild-type mice
• however, alveolar lumina are filled with milk
• mice treated with doxycycline from birth exhibit reduced ductal elongation compared with wild-type mice

growth/size/body
