hm1

• Allelic Composition: Qrfpr^tm1Lex/Qrfpr^tm1Lex
• Genetic Background: involves: 129S/SvEvBrd * C57BL/6J

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

skeleton

skeleton phenotype ( J:144011 )

N • in the femur the trochlear groove, epiphysis, growth plate, primary and secondary spongiosa, trabeculae and cortical bone are all similar to wild type mice

abnormal intervertebral disk morphology ( J:144011 )

• disks occupy larger spaces

abnormal nucleus pulposus morphology ( J:144011 )

• wider

kyphosis ( J:144011 )

• seen in most females and a few males

abnormal vertebrae morphology ( J:144011 )

• end plates display a wider hypertrophic zone and mildly disrupted calcified zone

• branching of trabeculae within the primary spongiosa is reduced and the trabeculae appear slightly thinner compared to controls

• the number of tartrate-resistant acid phosphatase positive cells is reduced especially in the secondary spongiosa

abnormal lumbar vertebrae morphology ( J:144011 )

• decrease in trabecular volume and connective density that is more severe in females than in males

abnormal vertebrae development ( J:144011 )

• results suggest an early arrest of osteochondral bone formation and reduced bone remodeling in the secondary spongiosa

decreased bone mineral density ( J:144011 )

• following ovariectomy the decrease in bone mineral density is greater in homozygous females compared to wild-type controls

• most of the difference in the decrease is attributable to a greater decrease in the bone mineral density of the spine

abnormal trabecular bone morphology ( J:144011 )

• in the vertebrae branching of trabeculae within the primary spongiosa is reduced and the trabeculae appear slightly thinner compared to controls
