Outline of Final Research Achievements

We have developed a technique to induce Schwann cells by introducing genes for two transcription factors, SOX10 and Krox20. By searching for small molecule alternatives to each of SOX10 and Krox20 in a large screening model, they were able to identify an alternative to Krox20. This allowed us to convert fibroblasts into schwann cell-like cells (mSCLC), which have the phenotype and function of Schwann cells. However, we were not able to identify a compound that can replace SOX10, which will be the subject of future research.

Academic Significance and Societal Importance of the Research Achievements

これまでの申請者の研究でSOX10とKrox20 の2種類の遺伝子を線維芽細胞に導入発現nさせることでシュワン細胞に転換することを発見したが、今回の申請分の検討ではこれらの2遺伝子に代わる化合物をスクローニングした。結果Krox20に代わる小分子化合物が同定され、これを用いることでシュワン細胞により類似したフェノタイプと機能を示すmSCLC
を創出することに成功した。この発見から、これまでより安全で容易にシュワン細胞を調整することが可能となり、今後の末梢神経再生に大きく利用価値があると考える。
