Myeloblast blood cell. Light micrograph of blood cells, including a myeloblast, a precursor for a type of white blood cell (leucocyte). Myeloblasts differentiate into granulocytes. This process is called granulopoiesis and occurs mainly in the bone marrow. Granulocytes, like all white blood cells, are part of the body's immune system. They are involved in the body's immune response, and contain granules with enzymes used to destroy pathogens. The surrounding cells are mostly red blood cells.
