Tumor-induced aberrant myelopoiesis gives rise to immunosuppressive myeloid cells such as MDSCs and TAMs, both of which potently inhibit anti-tumor immune responses (left). In the present study, Han et al. demonstrate tumor-induced erythroblast-like cells, named Ter-cells, drive tumor growth via secretion of artemin, providing a novel link between aberrant erythropoiesis and tumor progression (right).³
