| pubmed-article:16831948 | pubmed:abstractText | Skeletal tissues respond to the physical demands of their environment by altering the synthesis and organization of the extracellular matrix. These observations have major implications for how physical environmental demands result in the clinical observations of atrophy and hypertrophy, and how manipulation of the physical environment can be used therapeutically to stimulate repair. Electrical stimulation will be considered as a paradigm of how musculoskeletal tissues respond to physical stimuli. A model of demineralized bone matrix-induced endochondral ossification has been used because it epitomizes the cell biology of endochondral bone formation in a temporally consistent way. We have studied cartilage and bone matrix production, the temporal locus of cell responsiveness, signal dosimetry, and the synthesis of signaling cytokines (TGF-beta) using biochemical, immunohistochemical, and molecular techniques. Exposure to certain electrical environments enhances chondrocyte differentiation reflected as a temporal acceleration and quantitative increase of cartilage extracellular matrix, earlier onset of osteogenesis, and more mature trabecular bone. The cell pool competent to respond resides in the mesenchymal stage. The enhancement in chondrogenesis is associated with an increase in TGF-beta synthesis mediated at least in part by binding of the transcription factor AP-1 and may be modulated specifically by phosphorylation of JNK. The clinical practice of orthopedics has empirically created a variety of biophysical environments in attempts to optimize skeletal repair. We are beginning to understand the biological effects of biophysical stimulation and are now poised to replace empiricism with treatment paradigms based upon physiologic understandings of dose and biologic response. | lld:pubmed |
