Neutrophils are derived from myeloblasts. White blood cells can be divided into two lines of generation: The myeloid line and the lymphoid line. The myeloid line gives rise to a kind of white blood cell with characteristic azurophilic granules hence these are called granulocytes. Granulocytes include neutrophils, eosinophils, basophils, and monocytes. All four cells come from the immature cell from the myeloid cell line called myeloblasts. The myeloid line also gives rise to red blood cells and platelets.
The lymphoid line, on the other hand, gives rise to lymphocytes and natural killer cells.
