ossification predominates over intramembranous ossification in this region.
There are areas of bone formation by endochondral
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
