PMN-MDSCs Modulated by CCL20 from Cancer Cells Promoted Breast Cancer Cell Stemness through CXCL2-CXCR2 Pathway

Investigators observed that polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs) were remarkably enriched in tumor microenvironment of CCL20-overexpressing cancer cell orthotopic allograft tumors.
