mortality/aging
• while 70% of mice die at birth some survive to weaning
• 70% of mice die at birth

growth/size/body
• at E12.5, mice are 83% of wild-type in size
• at 1 month of age, surviving mice are 70% of wild-type weight
• at E18.5, mice are 67% of wild-type in size

embryo
• at E12.5, mice are 83% of wild-type in size
• at mid-gestation, placental weight is 60% to 67% of wild-type

respiratory system
• following recovery at E18.5, alveolar space is reduced compared to in wild-type mice indicating a failure of lungs to inflate
• recovered E18.5 mice fail to initiate or sustain strong and regular breathing unlike wild-type mice

nervous system
• despite all other organs being proportionally reduced according to decreased body size, the brain is the same size as in wild-type mice

homeostasis/metabolism
• in mice recovered at E18.5

skeleton
N
• mice exhibit normal vertebral bodies and femurs
