Explore the mechanism by which doxorubicin disrupts the bone marrow niche and affects hematopoietic stem cells.
Utilized single cell transcriptomics and multiplex cytokine assays
Administered doxorubicin to mice models to assess the impact on hematopoietic stem cells
Conducted flow cytometry analysis for T cell activation and function
Doxorubicin treatment led to persistent loss of hematopoietic stem cell quiescence
Increased interferon gamma levels and CD8+ T cell activation observed in bone marrow
Doxorubicin-induced vascular defects were rescued by blocking interferon gamma signaling
