Osteogenesis of mesenchymal stem cells to differentiate between bone marrow by multiple signaling pathways that control, directly or indirectly affect small related transcription factor 2 (runt-related transcription factor 2, Runx2) and osteoblast specific transcription factor (osterix, Osx), the expression of osteogenesis key transcription factors, such as in the development and regeneration of the bone, bone repair has played a key role in the process of reconstruction. These pathways play their mechanism of action, but also intertwined associated constitute a complex signal transduction network, but due to the limitations of research methods, the osteogenic differentiation related signaling pathways of the specific mechanism is still unclear, if you can clarify these different signaling pathways play to the role of their relevant mechanism and the relationship between various pathways and the mechanism study of osteogenesis differentiation is of great importance. This article will review the progress of various signaling pathways in the regulation of osteogenic differentiation of bone marrow mesenchymal stem cells.
