Hematopoietic Stem Cell Tropism Mediated Targeting of Breast Cancer Stem Cells via Alteration of Tumor Immune‐Microenvironment

subpopulations within the cancer microenvironment. Proteomics of migrated HSCs toward TNBC-CSCs/MCF-7 cells revealed significant upregulation of IL-7, Notch, and other proteins involved in T cell activation and migration pathways. Metabolomics of HSC-conditioned medium (HSC-CM)-treated CSCs/MCF-7 cells further demonstrated that HSC-CM arrests TNBC-CSC growth and cell cycle progression by altering the mitochondrial bioenergetics. This study highlights the potential of leveraging both HSCs and HSC-derived factors for personalized therapies targeting CSCs in TNBC.
