Grant-in-Aid for Research Activity start-up
This project aims to identify the nature and origin of ES cells. More specifically, we wanted to know how ES cells are derived from inner cell mass cells (the events that take place during ES cell derivation), and what kind of cells they originated from. To address these questions, we decided to generate multiple reporter mice and carried out live-cell imaging analysis. One of the reporter mice which we generated can visualize DNA methylation status in living condition. This reporter mouse was termed MethylRO(methylation probe in ROSA26locus) and deposited to RIKEN BRC. Using MethylRO, we discovered that DNA methylation pattern undergoes dynamic changes during early embryonic development, whereas DNA methylation pattern was fairly static in ES cells. We are now preparing to carry out live-cell imaging analysis of ES cell derivation process using this MethylROmouse embryo (Ueda et al.In preparation).
