Monocytes, dendritic cells (DCs) and macrophages have been classically categorized into the mononuclear phagocyte system (MPS) based on their similar functional and phenotypic characteristics. While an increasing amount of research has revealed substantial ontogenic and functional differences among these cells, the reasons behind their heterogeneity and strategic positioning in specific niches throughout the body are yet to be fully elucidated. In this review, we outline how recent advances in intravital imaging studies have dissected this phenomenon and have allowed us to appreciate how MPS cells exploit their regional niches to specialize and maximize their functional properties. Understanding their cellular behavior in each of their specialized microenvironment will eventually allow us to target specific cells and their behavioral patterns for improved vaccine and therapeutic purposes.
