Lung cancer-fueled emergency myelopoiesis is characterized by an increase of S100A9+ and LCN2+ hematopoietic stem and progenitor cells
This study reveals that lung cancer drives emergency myelopoiesis in the bone marrow by expanding S100A9+ and LCN2+ hematopoietic stem and progenitor cells, where S100A9 acts as an upstream regulator of LCN2 and represents a promising therapeutic target to inhibit tumor growth and overcome immunotherapy resistance.
