Cells of the mononuclear phagocyte system (MPS) are usually defined by particular functional or phenotypical characteristics. However, this has led to confusion in the field, as many of the criteria that are used to define a particular cell population may actually be shared with other cell types. In this Opinion article, the authors propose that a new nomenclature that is based on cell ontogeny could enable a more robust classification of MPS cells.
