| Outline of Final Research Achievements |
The molecular mechanisms underlying the acquisition and maintenance of cancer stem cell (CSC) properties in cancer cells is still unclear because of their rarity in clinical samples.
For establishing a system to develop new therapies and diagnostic technology targeting CSCs, this study aimed to uncover the molecular basis of CSC properties in induced colon CSCs derived from SW480 cells by introducing defined transcriptional factors. In this study, we elucidated the impact of each transduced factor on acquired biological properties in the induced colon CSCs, and also investigated essential genes for maintenance of CSC properties in the cells, using global gene expression profiling with microarray analysis.
