The goal of our laboratory is to gain new biological insights on how hematopoietic stem cell dormancy is regulated. Specifically, we aim to elucidate the mechanism by which vitamin A and Gpr signaling maintain the molecular and metabolic state of dormancy. Our future findings will provide unique in-depth insight into the functional signaling networks that regulates hematopoietic stem cell fate and it can be expected that we will provide pioneering therapeutic avenues for nutritional and hematological diseases. To address these biological questions, we are pursuing interdisciplinary projects which include the use of genetic mouse models, primary patient material in combination with state-of-the-art population and single-cell OMICs analysis.
