| Outline of Final Research Achievements |
The skill of producing platelets in vitro is needed for over tens of thousands of patients with various kinds of platelet disorders. In this study, we aimed to investigate relevance of metabolic systems to megakaryocyte(MK) differentiation and their regulatory mechanism in MK differentiation using preadipocytes isolated from subcutaneous adipose tissues of mice. In MK differentiation, we found characteristic metabolic alterations such as activation of glycolysis, increased cholesterol levels, and enhanced mitochondrial biogenesis. Moreover, hypoxia-inducible factor α (HIFα), a central transcription factor that controls adaptive response to hypoxic stress in normal and pathological conditions, do not affect MK differentiation unlike the regulation of the hematopoietic stem cells.
