Outline of Final Research Achievements

We performed codon optimization for the protein purification toward the clinical setting. Codon optimization improved the protein production without loss of bFGF activity. To attempt to apply the bone regeneration seeds to the sciatic nerve regeneration and cartilage regeneration, we developed a new collagen scaffold materials, oriented collagen tubes (OCT) for peripheral nerve regeneration and high density collagen scaffold (HDCS) for cartilage repair. bFGF-anchored OCTs promoted pheripheral nerve tissue repair and motor function. HDCS had higher collagen density, mechanical property, and ability to promote cartilage repair compared to existing collagen materials. These materials are promising agent for promoting musculoskeletal repair in the clinical setting.
