Bone tissue develops through a series of fine-tuned processes, and there are two modes of bone formation, referred to either as intramembranous or endochondral ossification. In intramembranous ossification, bones develop directly from condensations of mesenchymal cells, and the flat bones of the skull...
Bone development is the formation and growth of bones. New bone is formed by the action of specialised cells called osteoblasts and osteoclasts, either by directly laying down bone tissue into connective tissue or forming it from cartilage, such as during growth in length of long bones. Latest...
Primary chondrocytes derived from the long bones of 15.5 day old embryonic mice were treated with DEX or the vehicle control, and total RNA was isolated after 6 and 24 hrs of culture, respectively. Figure 1 Gene expression changes in DEX-treated primary chondrocytes. Microarray and quantitative ...
Long bone growth plate An area of differentiating tissue located near the ends of long bones that enables physiological lengthening of the bones. Axial skeleton The portion of the skeleton consisting of the bones of the head and vertebrae. Appendicular skeleton The portion of the skeleton consisting...
Context: Controversy exists on the effect of obesity on bone development during puberty. Objective: Our objective was to determine differences in volumetric bone mineral density (vBMD) and bone geometry in male obese adolescents (ObAs) in overlap with changes in bone maturation, muscle mass and fo...
These equations in combination with the simulation of the proliferative process and the cartilage cell growth (chondrogenesis) lead to a quite accurate simulation of the growth process of a long bone, even predicting the development of secondary ossification centers in the epiphysis. 展开 关键词: ...
Sequential Progression of the Differentiation Program by Bone Morphogenetic Protein-2 in Chondrogenic Cell Line ATDC5 During embryonic development of long bones, chondroprogenitor cells exhibit the transitions of phenotype, i.e., from type I collagen-expressing cells to ty...

4.1.1Bone morphogenic proteins 4 (BMP4) Bone Morphogenic Proteins 4 (BMP4) has a role in germ cell specification of the female genital tract [125].BMP4is a member of the TGFβ-superfamily family, plays a role in the regulation offolliculogenesisin the ovary [126]. Previous studies have ...
The half-century of lipophobia in the United States may be abating with some return of sanity on the discussion of health and dietary fat [Taubes, 2001]. The youngest victims of this collective, decades long madness are those infants deprived for one reason or another of breast milk. They...
