Immature granulocytic leukocyte (eosinophil, basophil, or neutrophil) normally found in bone marrow and present in the circulating blood in certain diseases especially myelocytic leukemia.
An immature cell in the bone marrow that produces leukocytes.
An immature form of granulocyte having a round nucleus (compare metamyelocyte) and neutrophil, eosinophil, or basophil granules in its cytoplasm (compare promyelocyte). It is normally found in the blood-forming tissue of the bone marrow, but may appear in the blood in a variety of diseases, including infections, infiltrations of the bone marrow, and certain leukemias.
The name given to one of the cells of bone marrow from which the granular white cells of the blood are produced. They are found in the blood in certain forms of leukaemia.
A large immature, granular blood cell from which leukocytes are derived.
A cell from the red bone marrow that gives rise to leukocytes. These cells can sometimes be found during serious infections and are abundantly present in the blood in instances of myeloid leukemia.
