Where Do Phagocytes Come from?

Phagocytes are bone marrow-derived cells of myeloid origin, including neutrophils, eosinophils, basophils, monocytes, and the mature form of the monocyte.

Where are phagocytes produced?

Phagocytes and Their Receptors

Phagocytes include neutrophils, macrophages, and dendritic cells (DCs), which have the capacity to engulf and digest relatively large particles on the order of 1–10 µm and even larger. In adults, these cells are generated from hematopoietic stem cells in the bone marrow.

What cells produce phagocytes?

In the blood, two types of white blood cells, neutrophilic leukocytes (microphages) and monocytes (macrophages), are phagocytic. Neutrophils are small, granular leukocytes that quickly appear at the site of a wound and ingest bacteria.
