basophil A type of white blood cell (leucocyte) that has a lobed nucleus surrounded by granular cytoplasm (see granulocyte). Basophils are produced continually by stem cells in the red bone marrow and move about in an amoeboid fashion. Like mast cells, they produce histamine and heparin as part of the body's defences at the site of an infection or injury (see inflammation).
