craniofacial
• 3D microCT analysis of neonatal craniofacial bones showed alterations in the shape and volume of the premaxilla, maxilla, palatine bone, frontal bone, and mandible
• however, alterations in the half width and height of craniofacial bones are generally mild or undetectable
• the frontal suture is dramatically affected, as the gap between the paired neonatal frontal bones is increased by 1.3-fold relative to controls
• the width of the anterior narrow side of the neonatal frontal bone is increased by ~132%, whereas the width of the posterior wide side is reduced by only 12%
• the volume and surface area of the frontal bones are reduced by ~18% and 23%, respectively
• frontal bone length is reduced by ~11% relative to controls
• however, height is not significantly altered
• newborns show a significant loss of alveolar bone around both maxillary and mandibular incisors
• the length of neonatal maxillary and mandibular incisors is severely reduced
• the volume of the neonatal mandible is reduced by ~35% relative to controls (J:264205)
• the volume of the neonatal mandible is reduced by ~35% relative to controls (J:264205)
• however, the width is not significantly altered (J:264205)
• mandibles show a 17% decrease in length, proportional to decrease in head size (J:289243)
• the palatine process of the neonatal maxilla is severely disrupted, as the gap between the paired palatine processes of the maxilla is increased by ~5-fold relative to controls
• neonatal premaxillae show a 12-14% reduction in length and a 20% reduction in height, whereas width is increased by 6% relative to controls
• both the angle and extension of the posterior tip of the premaxilla are affected, altering its shape
• the volume of the premaxilla is reduced by 25% relative to controls
• neonatal maxillae exhibit a much smaller body, with a 18% reduction in length, a 25% reduction in half width and a 16% decrease in height relative to controls
• the volume of the whole maxilla is reduced by ~30% relative to controls
• neonatal palatine bones show a 35% reduction in length, whereas the gap between the paired bones is increased by 25-86%
• the volume of the palatine bones is reduced by ~30% relative to controls
• however, the half width and height of the palatine bones are relatively normal
• the horizontal palatine bones are almost completely absent, consistent with the cleft palate phenotype
• at E12.5, RNA expression of Msx1 is significantly reduced in the frontal bone primordium and the developing mandible
• impaired proliferation of palatal mesenchymal cells
• delay in development at E14.5 but shelves have elevated at E15.5
• complete cleft palate with 100% penetrance
• proportional to decrease in head size
• show a 14.7% decrease in head length
