Identification of a Human Clonogenic Progenitor with Strict Monocyte Differentiation Potential: A Counterpart of Mouse cMoPs

Immunity. 2017 May 16;46(5):835-848.e4. doi: 10.1016/j.immuni.2017.04.019.


Monocytes give rise to macrophages and dendritic cells (DCs) under steady-state and inflammatory conditions, thereby contributing to host defense and tissue pathology. A common monocyte progenitor (cMoP) that is strictly committed to the monocyte lineage has been recently identified in mice. Here, we identified human cMoPs as a CLEC12AhiCD64hi subpopulation of conventional granulocyte-monocyte progenitors (cGMPs) in umbilical cord blood and in bone marrow. Human cMoPs gave rise to monocyte subsets without showing any potential for differentiating into myeloid or lymphoid cells. Within the cGMP population, we also identified revised GMPs that completely lacked DC and lymphoid potential. Collectively, our findings expand and revise the current understanding of human myeloid cell differentiation pathways.
