growth/size/body
• mice exhibit short limb dwarfism
|
• mice grow slower from birth
|
skeleton
• expansions of the hypertrophic zone are present at birth and are still apparent at 7 weeks of age
• the hypertrophic zone of tibial growth plates are expanded by 5-fold in 3 week old mice
|
• the angle of deflection of the ischial tuberosity is increased about 3-fold at 3 weeks of age, indicating hip dysplasia
|
• growth plates show disrupted hypertrophic chondrocyte differentiation, with recruitment of osteoclasts to the vascular invasion front and the height achieved by the terminal hypertrophic chondrocytes being reduced
|
• decrease in endochondral bone growth rate
|
cellular
• marker analysis indicates increased ER stress in the growth plate
