A myeloid stem cell becomes a red blood cell, a platelet, or a myeloblast, which then becomes a granulocyte (the types of granulocytes are eosinophils, basophils, and neutrophils). A lymphoid stem cell becomes a lymphoblast and then becomes a B lymphocyte, T lymphocyte, or natural killer cell. A B lymphocyte may become a plasma cell.
