Hypoxia induces transcriptomic changes in bone marrow cells leading to increased erythropoiesis [TFPI]

Erythropoiesis takes place mostly in bone marrow and ends in blood. Previous studies have shown that hypoxia has direct effects on the bone marrow, which could promotes erythropoiesis by modulating erythroid progenitor maturation. However, how bone marrow microenvironment participates in erythropoiesis under hypoxia still need further clarification. In this study, we analyzed transcriptional changes of bone marrow cells of mice exposed to 5000 m altitude hypoxia for 1 week. We profiled the top 20 up-regulated secreted factor genes after treatment with hypoxia, and found TFPI was one of the secreted factor genes with the highest expression. Bone marrow cells were obtained from mice exposed to 5000 m hypoxia for 1 week.
