Laboratory for Cell Asymmetry
Research Areas
| Asymmetric division gives rise to two differently fated cells from a single progenitor cell, and is a basic mechanism to generate cellular diversity, which is utilized in a variety of developmental contexts. During our study on genetic programs of Drosophila neural development, we have found that the asymmetric division of neural stem cells plays a pivotal role in specifying neural cell fates. Since then, we have focused on the mechanism of the asymmetric divisions of neural precursor cells and underlying cell polarity. We extend our analysis from Drosophila to vertebrates and aim to understand roles of cellular asymmetry in creating multi-cellular organisms. |  Group Director Fumio MATSUZAKI (Ph. D.)  |
