Extracellular Signaling Regulation on Neoblast Repopulation

报告摘要:

My research is focused on signaling mechanisms controlling in vivo stem cell repopulation. Planarians are free-living flatworms, capable of rapidly regenerating from any injury. This incredible ability relies on a proliferative population of cells called “neoblasts” that contain adult pluripotent stem cells. Remarkably, a single pluripotent stem cell surviving sublethal irradiation can repopulate the entire neoblast compartment and generate all types of differentiated cells in the animal’s body. The robust stem cell regulation and methodologies to effectively visualize neoblasts at whole animal resolution makes these organisms a powerful in vivo model system to achieve my research goal. I will take a multidisciplinary approach combining molecular biology, biochemistry, genetics, microscopy, and computational biology to uncover the signaling mechanisms conferring the in vivo neoblast repopulation in planarians and apply in mammals.
