| Research Abstract |
In this study, we produced the spontaneous differentiation, and then analyzed global changes of gene expression during the spontaneous differentiation using DNA microarray. As results of the microarray analysis using four human pluripotent stem cell lines, we found that some genes were commonly up- or down-regulated during the collapse of undifferentiated state. Furthermore, we analyzed the role of polycomb group during the collapse of undifferentiated state by ChIP-seq and ChIP-QPCR.
