Bone develops by intra-membranous and endochondral ossification. Intramembranous ossification occurs through the transformation of mesenchymal cells into osteoblasts, while in endochondral ossification a pre-existing cartilage forms first and then undergoes ossification. Two types of bone tissues form the ...
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...

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 ...
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...
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 ...
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 ...
Notably, the biomechanical strength of bone formed by intramembranous ossification is inferior to that of endochondral osteogenesis [16,30] (Figure 2). Figure 2. The process of intramembranous ossification. A small group of adjacent mesenchymal cells form a small cluster of cells and undergo ...
Marotti et al.270hypothesized that in human bone physiology, osteoblasts can participate in two different types of osteogenesis: static and dynamic osteogenesis. Static osteogenesis occurs in the mesenchymal tissue to initiate intramembranous ossification to generate primary trabecula during growth. This oste...
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 ...
