学习目标:
Myeloid cells, including monocytes/macrophages and neutrophils, are crucial regulators of tumor progression and response to cancer therapy. These cells are generally short-lived and must be continuously replenished to promote tumor progression. We found that circulating hematopoietic stem and progenitor cell (HSPC) from various cancer patients are myeloid biased, and serve as an important source of myeloid descendants in tumors. In various murine tumors, the spleen selectively recruits a population of HSPC and “educates” these cells to generate highly suppressive myeloid descendants. Abrogation of splenic myelopoiesis was not only sufficient but more effective than the tumor-targeted strategy in TME reshaping and tumor regression. This presentation will also discuss the spatial distribution of macrophages in tumors which could reveal the nature of the multifaceted roles of these cells in cancer progression.
