mortality/aging
• about 80% die soon after birth while 20% survive; those surviving do not exhibit cleft but have shorter faces
|
• about 80% die soon after birth due to facial cleft and cleft palate, however mice without cleft survive
|
embryo
• mutants show an increase in apoptosis in the developing frontal bone primordial mesenchymal cells at E10.5
• mutants exhibit a reduction in the number of frontal bone primordial cells at E12.5 but no changes in apoptosis or proliferation at this time
• the frontal bone primordial cells form the frontal bone matrix normally and differentiate into the frontal bones at E15.5, but their sizes are smaller
|
• cell density of the frontonasal mesenchyme is lower than in controls at E10.5 but not at E9.5
• an increase in apoptosis is seen in the frontonasal mesenchyme at E10.5
• however, proliferation is normal in this area
|

|
• 100% of mice exhibit wide-open anterior fontanelles at birth
|
• newborns show reduced size of the frontal bones in the presence and absence of cleft face and cleft palate
|
• nasal processes are smaller at E10.5

|
• 83.3% of newborns have midline fusion defects, cleft face and cleft palate
• mice without cleft have a short face, with facial length 0.87-fold shorter than controls at 3 weeks of age
|
• mice with cleft face and cleft palate exhibit more severe defects in craniofacial bone formation than those without, showing nasal bone dysplasia and septal cartilage separation
