Figure 3: Schematic diagram showing origin of tissue macrophages and dendritic cells. From hematopoietic stem cells in bone marrow, the myeloid system differentiates into mast cells, megakaryocytes, neutrophils, monocytes, etc. The monocyte further differentiates into macrophages and dendritic cells. These cells cross circulatory barrier and enter various tissues for local phagocytic activity
