Several data support the concept that skeletal homeostasis, repair and adaptation to daily life depend on mechanically-induced signals that promote appropriate responses of bone cells. This review considers the cells that are responsive to mechanical signals within the bone environment, and the molecular mechanisms involved in mechanotransduction, the process by which cells convert mechanical stimuli in biochemical signals and subsequently modify biological activity. Understanding the cellular and molecular mechanisms underlying bone responses to mechanical loads will positively impact current knowledge on basic bone biology and pathophysiology and will likely contribute to the development of new interventions to improve bone strength.

Introduction. Bone morphogenetic proteins (BMPs Bone Morphogenetic Proteins) are a group of growth factors with ability to induce the formation of bone and cartilage. Marshall Urist in 1965, was the first to describe bone morphogenetic activity. Objective. Is the assessment of histological response by the cell count of an experimental group to which they applied the numbers bone morphogenetic protein 2 (rhBMP-2) and one group was left as control. Material and methods. Wistar rats were used 26 to which they caused a defect in the body of the mandible bilaterally, the right side defect was applied bone morphogenetic protein-2 (rhBMP-2) and on the contralateral side was left normal bone healing. These histological evaluations were observed for five days, ie the first, second, third, fourth and sixth weeks, respectively. Results. The results of this study were based on cell counts (osteocytes, osteoblasts and osteoclasts), which are most representative cells in the bone matrix synthesis. In all groups compared, the experimental side was a higher number of precursor cells (osteoblasts), so we can conclude that the rhBMP2 actively participates in the synthesis of bone matrix, compared with bone healing that takes place as usual.

The bone is a dynamic tissue that provides mechanical support, physical protection, storage site for minerals, and enables genesis movement. The bone biology (osteobiology) is regulated by the balance between osteoblastic formation and osteoclastic resorption. The skeletal bone homeostasis is influenced by components of the bone marrow organ, neuroendocrine system and hemato-immune system. The purpose of this review is to describe the biodynamic of the bone organ, and actual terapeutics with platelet-rich plasma in guided bone regeneration, a co-surgical method employed to increase the quantity and quality of the bone.
