Final answer:
Auer rods would stain most strongly for myeloperoxidase as they are found within myeloblasts associated with acute myeloid leukemia, where myeloperoxidase is most abundantly present.
Step-by-step explanation:
The question asks which of the following would stain most strongly for myeloperoxidase: lymphoblasts, Auer rods, monocytes, or normal myeloblasts. Myeloperoxidase is an enzyme most abundantly present in neutrophil granulocytes, a type of white blood cell. It is also present in Auer rods, which are cytoplasmic inclusions typically found in myeloblasts in acute myeloid leukemia (AML). Therefore, the answer is B. Auer rods.
Myeloid stem cells give rise to several formed elements in the blood, including erythrocytes, megakaryocytes that produce platelets, and myeloblasts that develop into monocytes and granulocytes like neutrophils, eosinophils, and basophils. Impaired production of erythrocytes can be seen in patients with acute myelogenous leukemia due to damage to the myeloid stem cells. Neutrophils, as the most numerous leukocytes active against bacteria, are also derived from myeloid stem cells and would be affected by the condition.
