• at E15.5, no proliferating chondrocytes are observed at the center of the epiphysis or in the presumptive columnar zone in the humeri unlike in wild-type mice
|
• osteoblasts exhibit swelling of the endoplasmic reticulum unlike in wild-type cells
|
• at E13.5, hypertrophic chondrocytes are smaller than in wild-type mice
• at E13.5, proliferating chrondrocytes are larger than in wild-type mice
• at E15.5, chondrocytes fail to form an organized columnar growth zone compared with wild-type mice
• the chondrocyte hypertrophic differentiation is delayed compared to in wild-type mice and absent at E18.5
• chondrocytes exhibit swelling of the endoplasmic reticulum and abnormal golgi unlike in wild-type cells
|
• intramembranous and endochondral bone mineralization is delayed compared to in wild-type mice
|
• mice lack vertebral-body ossification unlike wild-type mice
|
• at E15.5, chondrocytes produce less extracellular matrix compared to wild-type cells
• at E15.5, no proliferating chondrocytes are observed at the center of the epiphysis or in the presumptive columnar zone in the humeri unlike in wild-type mice
• at E17.5, apoptotic chondrocytes are detected in the humeri unlike in wild-type mice
|
cellular
• mice exhibit swelling of the endoplasmic reticulum (ER) in the chondrocytes and osteoblasts unlike in wild-type cells
• however, the ER of other cells is normal
|
• post-translational protein processing and secretion in primary skin fibroblasts is impaired compared to in wild-type cells
|
respiratory system
• alveolar formation in the lungs is decreased compared to in wild-type mice
