N | normal phenotype |
• newborn mice display open eyelids
|
• at E10.5, the number of proliferating cells in the first branchial arch mesenchyme is reduced by ~25%
|
• newborn mice exhibit severe facial hypoplasia
|
• a mild size reduction of the upper lip is first seen at E13.5
|
• an up-turned nose is first seen at E13.5
|
• newborn mice have low-set ears
|
• proliferation of neural crest cells is reduced as early as E10.5; however, these cells continue to expand and are capable of differentiating into cartilage and bone, esp. in the distal region of the maxilla and mandible, respectively
|
• at E10.5, the number of proliferating cells in the first branchial arch mesenchyme is reduced by ~25%
|
• all neural crest cell-derived skull components are severely affected
|
• all neural crest cell-derived jaw components are severely affected
|
• a mild size reduction of the lower jaw is first seen at E13.5
|
• in newborn mice, the length of the mandible is only 49% of that in wild-type controls, i.e. significantly smaller than that of mice that are double homozygous for both Nipbltm1.1Hpt and Mau2tm1.1Hpt and hemizygous for Tg(Wnt1-cre)11Rth (68% of wild-type controls)
|
• surprisingly, newborn mice exhibit a more pronounced craniofacial phenotype relative to not only mice that are singly homozygous for Nipbltm1.1Hpt and hemizygous for Tg(Wnt1-cre)11Rth, but also to mice that are double homozygous for both Nipbltm1.1Hpt and Mau2tm1.1Hpt and hemizygous for Tg(Wnt1-cre)11Rth
