The bones, mainly some craniofacial bones, are formed by intramembranous ossification, a process in which bones form directly from condensations of mesenchymal cells without a cartilage intermediate. Whereas ch
45Figure 4shows microCT images with greatly increased femoral trabecular bone content in KO mice. In addition to influencing osteoclast function, S1P is also produced by osteoclasts and stimulates bone formation by osteoblasts.44,80Complete genetic rescue of the non-lymphoid lesions, including osteopetr...
2). Like most craniofacial bones, the palatal bones form by intramembranous ossification, which involves condensation of the neural crest derived mesenchyme cells that differentiate directly into osteoblasts. We carried out trichrome staining of serial paraffin sections to compare the cell condensation and...
During intramembranous ossification, compact and spongy bone develops directly from sheets of mesenchymal (undifferentiated) connective tissue. The flat bones of the face, most of the cranial bones, and the clavicles (collarbones) are formed via intramembranous ossification. The process begins when mese...
One being is endochondral ossification which is established within cartilage, is the most common way the majority of bones form. Secondly, intramembranous ossification structures the flat bones of the skull, clavicle, and mandible. Furthermore, the skeletal system manufactures blood cells, which the ...
Bone development is a critical aspect of human growth, with osteogenesis-angiogenesis coupling playing a pivotal role in this process. Bone formation occurs through two primary mechanisms: intramembranous ossification and endochondral ossification. During these processes, OBs and chondrocytes secrete VEGFA ...
Ex vivo bone organ cultures combine the advantages of animal models and cell cultures, providing a unique research option.34 Alveolar bone is formed through intramembranous ossification,35 and its histologic appearance, structure and biological characteristics are similar to those of calvaria. The ex ...

We analyzed the two bone tissue types, separately, because they are developed by distinctive mechanisms and may express different sets of ppGalNAcTs. Flat bones are formed by intramembranous ossification, where bone tissues are directly deposited onto condensed mesenchyme, whereas long bones are ...
Staining of skeletal preparations from newborn homozygous mutant mice with alcian blue and alizarin red indicated a virtual absence of mineralization in all facial and skull bones formed by intramembranous ossification (Figure 2H), whereas supraoccipital, exoocipital, basioccipital, basisphonoid, and ...
