Adult tissue stem cells produce highly differentiated but short-lived cells throughout life, contributing to the tissue maintenance and repair. To balance between stem cell self-renewal and differentiation, stem cell often divide asymmetrically to produce two distinct daughters. We investigate the molecular and cellular mechanisms that regulate asymmetric stem cell division using male and female Drosophila germline stem cell systems. We are currently focusing on several specific questions, 1) How the niche signal is the spatially restricted with the emphasis on the novel stem cell specific structure, MT (microtubule based)-nanotubes? 2) How are the physical obstacles (e.g., protein diffusion b?arrier) of dividing stem cells localized, and how does it contribute to precise fate asymmetry? 3) How does the niche monitors stem cell behavior to globally regulate stem cell activities? 4) Mechanism of stem cell clonal expansion. Taking the advantage of small size and simple anatomy of Drosophila gonads, we can conduct whole tissue live imaging to monitor in vivo stem cell behavior. We generate tools to investigate various protein dynamics in asymmetrically dividing stem cells. Our effort will contribute to comprehensively understand how the extrinsic and intrinsic regulations are integrated to ensure the precise cell fate determination.

We utilize Drosophila male and female germline stem cell system to study asymmetric division of the stem cell within the niche.

1) Characterizing niche ligands diffusion starting upon lysosomal inhibition and assessment of its impact on dedifferentiaiton of the stem cells.
2) Live imaging of asymmetric stem cell division organelle shuffling.
3) Establishment of the tools to study cell cycle progression by modulating the centrosome and microtubule organization within the living cell.
