Outline of Final Research Achievements |
We recently developed nanocarbon fiber sheets (NCFSs) made from electrospun nanosized carbon fiber. Here, we investigated the possibility of using NCFSs as a scaffold for bone regeneration by evaluating bone tissue compatibility and osteogenesis. NCFS scaffolding enabled good bone regeneration of skull defects in mice through interactions with the bone morphogenic protein rhBMP-2. In proliferation trials, osteoblasts showed good compatibility with NCFS, and ALP activity in culture assays with calcification medium indicated elevated differentiation of osteoblasts. Based on these findings, NCFSs may have potential bioapplications as a scaffold for bone regeneration.
