Outline of Final Research Achievements

Sets of specific transcription factors may induce cellular conversion from one committed cell to another. In the mesenchylmal cell lineages, the transcription factor MyoD can induce non-muscle cells to muscle cells. It is also reported that co-transfection of Sox9 with other sets of transcription factors may induce chondrocytes from non- chondrocytes. However reproducible and highly efficient cellular conversion from non- skeletal to skeletal cells is still challenging. In this study, we examined whether cellular conversion from non- skeletal to skeletal cells can be improved by using transactivation domain (TAD) of MyoD. Addition of TAD to Runx2 and sox9 enhanced activity of transcriptional transactivation. Cellular conversion rates by those factors did not change significantly, suggesting that additional factors or improvement of experimental condition are required for the cellular conversion of non- skeletal cells.
