← Human Body & HealthWhy does chronic erythropoietin deficiency in renal failure increase anemia risk, rather than stimulating increased red blood cell production?
A)Reduced B12 absorption occurs
B)Iron overload causes bone marrow suppression
C)Erythroid progenitor cell differentiation decreases✓
D)Reticulocyte maturation is prematurely terminated
💡 Explanation
Erythropoietin stimulates red blood cell production by binding to receptors on erythroid progenitor cells in the bone marrow, triggering their differentiation into red blood cells. Therefore, a deficiency of erythropoietin impairs this differentiation process, causing fewer red blood cells to be produced, rather than issues with B12, iron, or reticulocyte maturation.
