Extramedullary hematopoiesis occurs under which condition?

Extramedullary hematopoiesis is the body’s way of keeping blood cell production going when the bone marrow can’t meet its needs. The bone marrow is the normal site of hematopoiesis in adults, but if it becomes unable to produce enough cells—because of failure, fibrosis, infiltration by disease, or other serious stress—the body reactivates hematopoiesis in other sites such as the liver and spleen. That compensatory process explains why extramedullary hematopoiesis occurs: it’s not limited to a single trigger like aging or a specific treatment, and it isn’t confined to early fetal life.
