Abstract: Granulocyte-monocyte progenitors (GMPs) have been previously defined for their potentialto generate various myeloid progenies such as neutrophils and monocytes. Althoughstudies have proposed lineage heterogeneity within GMPs, it is unclear if committedprogenitors already exist among these progenitors and how they may behave differentlyduring inflammation. By combining single-cell transcriptomic and proteomic analyses,we identified the early committed progenitor within the GMPs responsible for the strictproduction of neutrophils, which we designate as proNeu1. Our dissection of the GMPhierarchy led us to further identify a previously unknown intermediate proNeu2 population.Similar populations could be detected in human samples. proNeu1s, but not proNeu2s,selectively expanded during the early phase of sepsis at the expense of monocytes.Collectively, our findings help shape the neutrophil maturation trajectory roadmapand challenge the current definition of GMPs.
