Outline of Final Research Achievements |
Hematopoietic stem cells (HSCs) exhibit multilineage differentiation and self-renewal activities that maintain the entire hematopoietic system during an organism's lifetime. These abilities are sustained by intrinsic transcriptional programs and extrinsic cues from the microenvironment or niche. In this study we have clarified a pivotal role of proryl hydroxylase (Phd) family genes in maintenance of stem cell capacity, cell cycle, and transplantation ability of HSCs. We also clarified a crucial role of hypoxia-inducible factor expressed in niche cells in generation of differentiated hematopoietic cells.
