| Outline of Final Research Achievements |
Direct reprogramming, whereby cells are directly converted into another functional cell types, occurs primarily in mesenchymal cells but not readily in other somatic cells. In this study, our objective was to develop a direct reprogramming approach utilizing epithelial-mesenchymal transition (EMT) for various somatic cells. We identified transcription factors that induce EMT in keratinocytes, and demonstrated that the expression of SOX10, along with EMT induction, directly converted keratinocytes into neural crest-like cells. Additionally, we successfully converted mammary epithelial cells into neural crest-like cells using this method.
