Research Abstract

肝細胞増殖因子(hepatocyte growth factor : HGF)は、中村らにより精製・クローニングされた多彩な機能をもつ増殖因子である。本研究ではHGFの再生能力をより強力に発揮させるための再生医療技術として、徐放技術を用いたドラッグデリバリーシステム(DDS : drug delivery system)を採用することとした。DDSは体内に投与したHGFが時間をかけて徐々に放出されるようにデザインされたもので、徐放化にはゼラチンハイドロゲルを用いる。本研究ではこのゲルを蝸牛正円窓から作用させることで、内耳有毛細胞に対する低侵襲・高度選択的なHGF投与を実現した。
