In patients with lymphomas, the cancer cells invade the bone marrow and destroy the environment required for normal hematopoiesis. This leads to bone marrow failure, which disrupts the production of hematopoietic cell lineages. All of the following cell types would be affected by this EXCEPT:
A) Red blood cells
B) Macrophages
C) Lymphocytes
D) Endothelial cells
E) Granulocytes

Question

Quizplus · Accepted Answer

Endothelial cells are not part of the hematopoietic cell lineages and thus would not be affected by bone marrow failure in lymphomas. Red blood cells, lymphocytes, macrophages, and granulocytes are all produced through hematopoiesis and would be affected by bone marrow failure.
