Our long term goal is to understand the molecular mechanism of asymmetric stem cell division.
Asymmetric stem cell division is a mechanism that balances stem cell self-renewal and differentiation through the production of one stem cell and one differentiating cell. It is a simple way of maintaining the stem cell population without increasing it and is thus thought to be a vital mechanism for tissue homeostasis and tumor suppression. My research goal is to elucidate the molecular mechanism as to how two daughter cells of different fates are made after only one cell division. My lab primarily uses Drosophila gonads, in which we can monitor asymmetric division in vivo. Owning to the simple anatomy and abundant imaging tools, this system allows us to discover previously unrecognized regulatory mechanisms Our research findings should lead to the development of new therapeutic approaches for cancers and degenerative diseases.
