The mononuclear phagocyte system constitutes macrophage cells spread throughout the human body. The macrophages are long-lived cells that provide a major defense system against hostile elements through phagocytosis and subsequent intracellular destruction of the particle or cell.
Commitment to the mononuclear phagocyte lineage is determined at the stage of the macrophage and DC progenitor (MDP), at which point, erythroid, megakaryocyte, lymphoid and granulocyte fates have been precluded (Fig. 1). MDPs give rise to monocytes and common DC progenitors (CDPs).
