Abstract

The skeletal system of mammals contains a set of cells, which in a hierarchical manner, maintain bone formation during the life. In this context, we know that osteogenesis is essential for bone renewal, as well as the bone healing through regenerative mechanisms; we know that these processes often decrease with the progress of age, leading to bone loss and an increased incidence of fractures. Currently, bone defects constitute a public health problem when the life expectancy of the population has increased significantly. Rebuilding the lost tissue is one of the great challenges of surgeons in the area, often requiring the application of a biomaterial that allows functional repair of lost tissue. Despite its medical, social and economic importance, little progress has been made regarding methodologies able to elect new therapies. We now know that the development and bone regeneration is a complex event and orchestrated by paracrine mechanisms of intercellular signaling showing that osteogenesis is coupled to angiogenesis since from the elegant work led by Prof. R. H. Adams of the Max Planck Institute for Molecular Biomedicine, recently published in Nature. In this context, our project aims characterize epigenetic alterations triggered by paracrine factors produced by endothelial cells in osteoblastic cells. To note, this application is linked with a current financing project from FAPESP (JP: 2014 / 22689-3), where our objective is to map the repertoire of molecules secreted by osteoblasts and endothelial cells and identify their effects each other during bone remodeling. Thus, we are grateful with the interest from Dr. Rodrigo since he has skills on cell biology, microscopy and epigenetic field.
