← Human Body & HealthWhy does allogeneic hematopoietic stem cell transplantation, following myeloablative conditioning, represent a curative treatment for patients with severe aplastic anemia?
A)Erythropoietin production increases dramatically
B)Donor cells restore normal hematopoiesis✓
C)B12 absorption becomes more efficient
D)Iron overload is reduced significantly
💡 Explanation
Hematopoietic stem cell transplantation restores hematopoiesis because the donor cells replace the patient's damaged bone marrow, therefore overcoming the underlying aplastic anemia. Rather than increasing erythropoietin or influencing B12/iron levels directly, the transplant addresses the root cause.
