  Purpose

The repair of large osseous defects remains still unsolved. Aim of this study is to isolate and cultivate fat-derived progenitor cells and differentiation into osteoblasts. Therefore, our research idea is to pre-engineer large synthetic bone grafts and study the vascularization process in vivo.
