Bone development in Japanese quail
The Anatomical Record, 1963AbstractThe development of the long bones of Japanese Quail was studied histologically and microradiographically at different post‐hatching periods from birth to one year of age. At the level of the mid‐shaft, the woven bone of the neonatal animal becomes thicker by rapid periosteal growth and becomes consolidated by the deposition of bone within large

Archives of Surgery, 1928
In the studies here recounted, three different aspects of the problems involved in the development of bone are discussed, as indicated in the title. All three studies are closely interwoven and cannot be considered separately without much needless repetition and reduplication.

Bone development in neurofibromatosis 1
Medical Hypotheses, 2003Bony abnormalities are common findings in cases of neurofibromatosis 1. We might hypothesize that neurofibromin, the protein encoded by the neurofibromatosis 1 gene, plays important roles in bone development. Loss of function of oligodendrocyte-myelin glycoprotein gene and increased activity of ras p21 might increase the level of c-fos proto-oncogene ...

Bone Structure, Development and Bone Biology
2009The skeleton serves as a structural support system. It has mechanisms to grow and change in shape and size to suit varying mechanical forces. It is involved in the calcium/phosphate balance and in the detoxification of heavy metals. Bone tissue is continuously formed and remodeled throughout life.

Disturbances of Bone Growth and Development
Radiologic Clinics of North America, 1988"What is growth anyway? Can one talk about positive growth in childhood, neutral growth in maturity, and negative growth in old age?" Our goal is to help promote normal positive growth in infants and children. To achieve this, we must be cognizant of the morphologic changes of both normal and abnormal bone formation as they are reflected in the ...

New developments in bone formation
Current Opinion in Nephrology and Hypertension, 1998Two independent strategies have established that the transcription factor, Cbfa1, is a key regulator of both osteoblast differentiation and osteoblast-specific gene expression. Gene targeting experiments in mice have also shown that haploinsufficiency of Cbfa1 expression causes symptoms reminiscent of the Cleidocranial dysplasia syndrome (CCD), a ...

Effect of Hormones on Bone Development
Annual Review of Pharmacology, 1972growth depends on continuation of cartilage growth and endochrondral oss ification at the epiphyses, while appositional growth and the lifelong remodeling of the skeleton depends on direct bone formation and resorption without the intervention of cartilage (l). These processes are subject to at least three kinds of regulation.

Bone morphogenetic proteins in development
Current Opinion in Genetics & Development, 1996The bone morphogenetic proteins (BMPs) constitute a large family of cytokines related to members of the transforming growth factor-beta superfamily. Recent evidence, in particular from gene targeting experiments in the mouse, indicates that BMPs are required for mesoderm formation and for the development and patterning of many different organ systems ...

Immunologic Regulation of Bone Development
2007A regulatory network comprised of transcription factors PU.1, Ikaros, E2A, EBF, and Pax5 control B cell fate specification and differentiation. Early B Cell Factor-1 (EBF-1) is essential for B cell fate specification while Pax5 is required for B cell development.
