A large white blood cell with finely granulated chromatin dispersed throughout the nucleus that is formed in the bone marrow, enters the blood, and migrates into the connective tissue where it differentiates into a macrophage.
A type of bone marrow -derived circulating blood cell that is the precursor of tissue macrophages. Monocytes are actively recruited into inflammatory sites, where they differentiate into macrophages or in the case of CNS, in perivascular macrophages.
Largest white blood cell containing a large eccentric nucleus, usually with a noticeable indentation, and pale cytoplasm. Monocytes are thought to become macrophages when they migrate into surrounding connective tissue.
A monocyte is the largest form of white blood cell with a kidney-shaped nucleus; its function is the ingestion of foreign particles such as bacteria and tissue debris. Monocytes belong to the group of phagocytes.
The largest type of leukocyte in circulation. These cells have more protoplasm than a lymphocyte. In cell counters these cells are usually sized between lymphocytes and granulocytes, due to the effects of lyse and diluent. Sometimes called midcells.
