The last 5 yr have witnessed major progress in skeleton biology. One of these areas of progress has been the partial elucidation of the transcriptional mechanisms of osteoblast differentiation and their conservation between mouse and human. Cbfal, or runx2, a homolog of the Drosophila Runt protein serves both as the earliest transcriptional regulator of osteoblast differentiation and as control...
Distraction osteogenesis biologically resembles fracture healing with distinctive characteristics notably in the distraction phase of osteogenesis. In the latency phase of bone lengthening, like in the inflammatory phase of fracture repair, interleukines are released and act with growth factors released from platelets in the local haematoma, leading to attraction, proliferation and differentiat...
Skeletal scintigraphy, which has now been established as a useful and accurate method of detecting early skeletal metastases and assessing their response to treatment, has been investigated for its pathological basis. Histological examination of several hyndred necropsy specimens, from sixty-eight patients who died from malignant disease, showed a significant increase of osteoid and immature wo...
Genetic studies have identified a high bone mass of phenotype in both human and mouse when canonical Wnt signaling is increased. Secreted frizzled related protein 1 (sFRP1) is one of several Wnt antagonists and among the loss-of-function mouse models in which 32-week-old mice exhibit a high bone mass phenotype. Here we show that impact fracture healing is enhanced in this mouse model of increas...
BACKGROUND p38 MAPK activity plays an important role in several steps of the osteoblast lineage progression through activation of osteoblast-specific transcription factors and it is also essential for the acquisition of the osteoblast phenotype in early development. Although reports indicate p38 signalling plays a role in early skeletal development, its specific contributions to adult bone remo...
