Endochondral ossification predominates over intramembranous ossification in this region.
There are areas of bone formation by
endochondral ossification.
Reappraisal of mesenchymal chondrosarcoma: novel morphologic observations of the hyaline cartilage and
endochondral ossification and [beta]-catenin, Sox9, and osteocalcin immunostaining of 22 cases.
Anionic molecules of the GAGs chondroitin sulfate in the growth plate have been reported to have important roles as ion exchangers in
endochondral bone formation (Hunter, 1991).
11,16) There are a few reported cases of involvement of the skull base (a site of
endochondral ossification), but these occur in advanced stages.
RXR binds to bone morphogenetic proteins (BMP) which substantially affect the process of complete maturation and hypertrophy of chondrocytes in the
endochondral ossification pathway (Enomoto-Iwamoto et al.
Dysplasia of
endochondral ossification, affecting secondary spongiosa, are characterized by errors in resorption or remodeling of secondary spongiosa, which results in focal densities and/or striations within the trabecular bone (3).
These cartilage models are later replaced by bone through
endochondral ossification (OLSEN et al.
The results were compared with two samples of bone (one
endochondral, one dermal) from a modern animal.
Several cellular mechanisms have been proposed to be affected by PEMF including an increased mineralization, collagen production,
endochondral ossiication and decreased osteoclastogenesis (7).
Acceleration of experimental
endochondral ossification by biophysical stimulation of the progenitor cell pool.
Impaired fracture healing in the absence of TNF-alpha signaling: the role of TNF-alpha in
endochondral cartilage resorption.
