Our long term goal is to understand the regulatory mechanisms 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 how differently fated two daughter cells 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 allow us to discover previously unrecognized regulatory mechanisms and thus contribute to develop a new therapeutic approach for cancers and degenerative diseases.

Accepting Lab Rotation Students: The Drosophila germline stem cell system is an excellent model to monitor stem cell behavior while they are still located in the niche. We use a combination of approaches including CRISPR genome engineering, genetics, and quantitative and whole-mount live imaging to understand adult stem cell regulation. Results from our research are relevant to human physiology and diseases, as many of the molecules that control Drosophila stem cell system are conserved in humans.
- Understanding the flexibility of niche-stem cell interaction: Tissue stem cells are under dynamic state that is largely governed by their microenvironment, or the niche, which facilitates plasticity and adaptability of stem cells to changing conditions. The aim of 1st rotation project is to investigate dynamics of cell signaling and downstream pathway activation in Drosophila germline stem cells, while they are adapting to various physiological and pathological conditions, including dietary changes, abnormalities in nervous system, methabolic disorders and aging.
- Visualizing chromosome interaction and gene expression change in stem cell systems: Dysregulation in stem-cell gene transcriptional program leads to abberent tissue homeostasis, and then human diseases such as cancer. Growing number of evidences suggest that diversification of regulatory elements is a major source of phenotypic polymorphism among population. These DNA elements interact not only with transcription factors and other regulatory proteins, but also with other DNA elements. Our recent study identified that interhomolog interaction of stem cell gene locus is uniquely regulated and is essential for prompt downregulation of the transcript. While biological importance of interchromosomal interaction is becoming increasingly clear in recent years, very little is known about the mechanism in the control of gene expression. The 2nd rotation project is to establish the tools for monitoring homolog interaction and gene expression simutaniously, by using MS2/MCP, PP7/PCP based visualization and quantification of nascent transcripts.
