Limb phenotype of Shox2tm1Ddu/Shox2tm1.1Ddu Tg(Prrx1-cre)1Cjt mice
mortality/aging
N |
• provided adequate access to food and water homozygotes are viable
|
limbs/digits/tail
|
• development of the forelimb stylopod elements is severely impaired; however development of the forelimb zeugopd elements is similar to wild-type mice
|
|
• development of the hindlimb stylopod elements is severely impaired
|
|
• the hindlimb zeugopod is also shorter
|
|
• virtually absent at birth with only a small abnormal dorsal piece remaining that does not span the axis of the limb
|
|
• virtually absent at birth with only a tiny cartilage analage which lacks ossification is seen; in adults ossification is seen but little bone growth occurs
|
skeleton
|
• virtually absent at birth with only a small abnormal dorsal piece remaining that does not span the axis of the limb
|
|
• virtually absent at birth with only a tiny cartilage analage which lacks ossification is seen; in adults ossification is seen but little bone growth occurs
|
|
• hypertrophic chondrocytes eventually appear in the humerus but are in abnormal asymmetric locations blocking formation of the growth plate
|
|
• at E12.5, the humerus and femur cartilages are already significantly shorter (by about 50%) than in wild-type
• by E14.5 the humerus and femur cartilage malformation is as severe as in newborns
• chondrocyte differentiation in the humerus is impaired with markers for immature cells (Col2a1) still present at E18.5 and expression of later markers greatly decreased or absent
