Basic Information image



Definition


Neutrophils are the most common white blood cells in the horse. They are of granulocytic origin and are important in bacterial infection and the innate immune response. These cells have a lobulated nucleus, usually three to four lobules, and pale basophilic cytoplasm with poorly staining granules.

Physiology




• Neutrophils originate from myeloid precursors in the bone marrow. There are three pools of cells in the bone marrow:


image The proliferative pool, which consists of dividing cells, myeloblasts, promyelocytes, and myelocytes

image The maturation pool, which consists of metamyelocytes and bands

image The storage pool, which consists of mature neutrophils and some bands. This is the first group of cells to head out into the peripheral blood when needed.

• Within the peripheral blood, there are two pools, the circulating pool and the marginating pool:


image The circulating pool are those cells that are counted in the complete blood count (CBC).

image The marginating pool are cells that are preparing to leave the blood and enter the tissue.
