Outline of Final Research Achievements |
One of the features of hematopoietic stem cells (HSCs) is “mobility”. In MDS/MPN, normal HSCs are gradually replaced with abnormal ones in the bone marrow. This phenomenon has never been analyzed in the aspect of HSC mobility. The aim of this research is to elucidate signaling relays that govern the HSC mobility in normal and diseased hematopoietic tissues. In the study of murine model of G-CSF-induced HSC mobilization from bone marrow to circulation, we found that FGF23 from erythroblasts and PPARδ in neutrophils strikingly regulate HSC mobility. Currently, the exact roles of these pathways in the maintenance/replacement of HSCs in MDS/MPN are under investigation by generating cell specific conditional knockout mice.
