MPN NSC failed to express granulocyte colony‐stimulating factor receptor CD114, macrophage colony‐stimulating factor receptor CD115, the GM‐CSF/IL‐3/IL‐5 receptor beta chain CD131, nerve growth factor receptor CD271, vascular endothelial growth factor receptor CD309, MET, and oncostatin‐M receptor (Figure S6). Here, CSF2 is linked to myeloproliferative disorder.
