N | normal phenotype |
• weight was 10-20% less than normal littermates
|
• caudal vertebrae shorter than normal and bone is less dense
• 2 centers of ossification in tail vertebrae and asymmetrical growth leads to kinks
• by E15.5, vertebral bodies of tail were narrower and more rectangular, fewer differentiated chondrocytes
|
• 80% of homozygotes with multiple kinks
|
• caudal vertebrae shorter than normal and bone is less dense
• 2 centers of ossification in tail vertebrae and asymmetrical growth leads to kinks
• by E15.5, vertebral bodies of tail were narrower and more rectangular, fewer differentiated chondrocytes
|
• abnormal development and increased intervertebral tissue
