Research Interests
The long-term interest of the Lee lab is to understand how stem and progenitor cells integrate multiple environmental signals to make cell-fate decisions under normal and pathological / stressed conditions. While somatic stem cells are often quiescent, lineage-committed progenitor cells play a key role in tissue regeneration and maintaining tissue homeostasis. These lineage-committed progenitor cells with limited self-renewal potential can respond to extrinsic and intrinsic signaling cues, and decide whether to undergo self-renewal or a differentiation division. Blood is one of the tissues with a high capacity of regeneration. Replenishment of RBCs is particularly active in order to ensure sufficient tissue oxygen supply. Therefore, generation of red blood cells (erythropoiesis) represents an ideal system to investigate how dividing progenitor cells maintain self-renewal capacity, and importantly, how self-renewal capacity can be retained or promoted for therapeutic purposes. Our lab uses primary erythroid progenitors as a paradigm to dissect the molecular basis that determines cell self-renewal or differentiation, which will provide insights of developmental decision in normal stem and progenitor cells or leukemic stem cells.
