skeleton
• resorptive bone surfaces poorly defined with a broad fringe of demineralized matrix
• osteoclasts seeded onto dentine sections develop shallower pits with thicker layers of unprocessed residual matrix
|
• diaphyseal cortical bone is less readily distinguished from subjacent trabecular bone
|
• increased height of tibial growth plates
|
• external form of bones is more gracile
|
• dense trabeculation of bone marrow spaces in long bones particularly in regions of rapid longitudinal growth, distal femur and proximal tibia
• retention of cancellous bone in the shafts of long bones
• primary spongiosa of vertebrae is retained as well
• plates of bone more common than in controls where thinner rods are more typical

respiratory system
• untreated mice with 20% thicker alveolar walls
• 1.5X greater collagen concentrations than in controls
|
• more pronounced alveolar wall remodeling after bleomycin administration, increased 18% as opposed to 6% in controls
• collagen concentration increased 3 fold as opposed to 2 fold in controls
|
immune system
• resorptive bone surfaces poorly defined with a broad fringe of demineralized matrix
• osteoclasts seeded onto dentine sections develop shallower pits with thicker layers of unprocessed residual matrix
|
hematopoietic system
• resorptive bone surfaces poorly defined with a broad fringe of demineralized matrix
• osteoclasts seeded onto dentine sections develop shallower pits with thicker layers of unprocessed residual matrix

homeostasis/metabolism
amyloidosis
(

)
• significantly larger amounts of amyloid deposited in the spleen
• amyloid deposits of smaller sized protein
