• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

skeleton

osteoarthritis ( J:112002 )

• rare in knee cartilage at 18 weeks of age

• present in 100% of year old mice as opposed to 45% of controls who also suffer from less severe symptoms

abnormal long bone epiphyseal plate proliferative zone ( J:112002 )

• hypertrophic zone of the proximal growth plate of tibia expanded 47% relative to controls at E16.5 and E17.5

• expansion attenuated during perinatal development and becomes normal in newborns

• chondrocytes in proximal growth plate exit the cell cycle early

• at E16.5, chondrocytes undergo premature differentiation to hypertrophic stage

increased bone mass ( J:112002 )

• whole body bone mass density measurements significantly elevated by 18 weeks of age

• bone mass density measurements for the knee joint are elevated by 7 weeks of age

immune system

osteoarthritis ( J:112002 )

• rare in knee cartilage at 18 weeks of age

• present in 100% of year old mice as opposed to 45% of controls who also suffer from less severe symptoms
