Ask A Scientist: What’s the Difference Between Human Monocytes and Macrophages? | Charles River

Monocytes and macrophages are very closely related cells with a few important distinctions and different use cases. Put simply, monocytes are macrophages in the blood; macrophages are monocytes in tissue. Monocytes are the largest type of white blood cells and play an important role in the adaptive immunity process. Monocytes typically circulate through the blood for 1–3 days before migrating into tissues, where they become macrophages or dendritic cells. Macrophages are monocytes that have migrated from the bloodstream into any tissue in the body. Here they aid in phagocytosis to eliminate harmful materials such as foreign substances, cellular debris and cancer cells. Macrophages take on various names depending on the tissue to which they migrated: These subpopulations of macrophages have functional differences due to environmental signals but are all part of the same macrophage family. Our monocytes are purified from peripheral blood and are versatile enough to meet your exact needs.
