Upregulation of interleukin 6 and granulocyte colony-stimulating factor receptors by transcription factor ccaat enhancer binding protein α (c/ebpα) is critical for granulopoiesis... The observed failure of granulopoiesis could be rescued by the addition of soluble IL-6 receptor and IL-6 or by retroviral transduction of G-CSF receptors, demonstrating that loss of both of these receptors contributes to the absolute block in granulocyte maturation observed in C/EBPα-deficient hematopoietic cells....
