Question

Myeloid stem cells may differentiate into myeloblasts, which mature into granulocytes, e.g. neutrophils, basophils, eosinophils. What are the possible options for the differentiation of myeloid stem cells?

1) Lymphocytes
2) Monocytes
3) Erythrocytes
4) Platelets

Answer 1

Myeloid stem cells can differentiate into monocytes, erythrocytes, and platelets. They do not give rise to lymphocytes, which come from lymphoid stem cells.

Step-by-step explanation:

Myeloid stem cells are a type of hemopoietic stem cell that have the capacity to differentiate into several types of blood cells.

These cells can develop into erythrocytes (red blood cells), produce megakaryocytes that subsequently produce platelets, and form a lineage that gives rise to monocytes and three types of granular leukocytes: neutrophils, eosinophils, and basophils.

Monocytes can mature into macrophages, which are phagocytic cells important for immune defense. In contrast, lymphocytes are derived from lymphoid stem cells, not myeloid stem cells. Therefore, the possible options for the differentiation of myeloid stem cells include 2) Monocytes, 3) Erythrocytes, and 4) Platelets, but not 1) Lymphocytes, as the latter arise from lymphoid stem cells.
