Erythroid precursors regulate local oxygen tension and repair outcomes in the bone marrow niche

Proceedings of the National Academy of Sciences, Volume 122, Issue 46, November 2025. <br/>SignificanceThis study reveals that erythroid precursor cells modulate oxygen levels in the bone marrow niche under both homeostatic and regenerative contexts. We show that bone marrow injury, such as bone fracture, locally activates erythroid precursors …
