Outline of Final Research Achievements |
Hematopoietic stem cells (HSCs) are defined as cells having self-renewal capacity and multipotency. HSCs regulate blood production throughout life. Rapid depletion of blood cells, such as through anticancer therapy, triggers stress hematopoiesis as a compensatory mechanism. However, the repeated occurrence of stress hematopoiesis poses potential risks, including the development of hematological malignancies and hematopoietic failure. Despite these concerns, the mechanism underlying stress hematopoiesis has not yet been elucidated. In this study, we have developed an original system to elucidate one aspect of the regulatory mechanism governing stress hematopoiesis.

Academic Significance and Societal Importance of the Research Achievements |
造血幹細胞は、急激な外的変化(ストレス)に対してストレス造血を行うことで造血系の恒常性を維持する。一方で、ストレス造血が繰り返し生じることは、血液腫瘍や造血不全発症のリスクになる可能性が示唆されている。そのため、ストレス造血が制御される機構を明らかにすることは、造血器疾患を予防する上で非常に重要である。本研究では、造血ストレスが造血幹細胞に及ぼす機能変化を明らかとしストレス造血を制御する機構の一端を示した。この結果は、造血器疾患の予防や造血幹細胞を用いた治療法の発展に貢献することが期待される。
