mortality/aging
neonatal lethality ( J:183999 )
• embryos are recovered at every embryonic stage examined, and are born live, but most die within the first postnatal day

embryo
embryo phenotype ( J:183999 )
N
• double mutants with wild-type (Sox2-cre E2f7fl/- E28fl/-) placentas appear normal at E10.5 and lack the developmental phenotypes in double null embryos
• Note: Sox2-cre is expressed only in the inner cell mass with no extraembronic tissue expression so the placentas are normal
• however, embryos rescued from lethality during development die within a few days of birth
abnormal embryonic tissue morphology ( J:183999 )
• significant numbers of apoptotic cells are detected in branchial arches and somites at E10.5

respiratory system
abnormal respiratory system morphology ( J:183999 )
• significant ectopic proliferation and apoptosis of pulmonary cells is observed in lungs at P1, but lungs do not appear overtly hypoplastic
