The skeletal system, which is made up of bone and cartilage, serves three primary functions: Mechanical support for sites of muscle attachment Protection of vital organs Ion reserve of Ca and PO for metabolic functions Bone Cells and Matrix Bone is a tissue in which the extracellular matrix has been hardened to accommodate a supporting function.
BMP treatment for acute open tibial fractures may be more favorable economically Combination of BMP-7 with a type-one collagen carrier has been the subject of increasing interest. BMP-7 in combination with osteosynthesis revision and bone grafting, or with bone grafting alone, shows that there is no perioperative or postoperative complications in patients With the use of BMPs increasingly accepted in spinal fusion surgeries, other therapeutic approaches targeting BMP signaling are emerging beyond applications to skeletal disorders.
BMP-7 is also regarded as a strong candidate for the clinical treatment of chronic kidney disease CKD Administration of BMP-7 prevents the development of adynamic bone disease in a preclinical model of chronic kidney failure For instance, GDF has emerged as a prognostic biomarker in acute coronary syndrome trial populations and in cardiac and vascular dysfunction and disease GDF may be a novel diagnostic and prognostic biomarker in patients with colorectal cancer Additionally, GDF-5 has emerged as a therapeutic target for rheumatic diseases These engineered biomaterials for enhanced bone regneration are in the initial trial stage of development.
The signaling relays in each stage ligands, receptors, Smads are responsible for the final target gene expression. More importantly, with the aging population expected to double over the next decade, the number of people suffering from osteoporosis is likely to increase dramatically and so is the cost of Medicare.
As such, there is increased pressure to elucidate the pathophysiology of bone diseases and the molecular mechanisms of skeletal remodeling in health and disease. So far, BMPand BMPcontaining osteogenic implants have been used in over one million patients worldwide for the treatment of long bone nonunions, spinal fusions, and acute fractures.
Apart from their recognized role in bone regeneration, BMPs have been used systemically to improve skeletal volume, kidney regeneration, glucose, and iron metabolism.

The biological process consists of several distinct temporal phases. In intramembranous ossification, bone develops directly from sheets of mesenchymal connective tissue, but in endochondral ossification, bone develops by replacing hyaline cartilage.
Intramembranous ossification is complete by the end of the adolescent growth spurt, while endochondral ossification lasts into young adulthood. Intramembranous ossification takes place within the womb and is the process by which flat bones such as some of the bones of the skull and the collarbones are created from connective tissue.
It also is the process for injured bones to heal and occurs when bones . • Intramembranous ossification – forms many _____(bones of skull and clavicles) – formed within a mesenchymal _____ – spongy bone ossifies before outer compact bone layers.
