After the bone marrow infusion, what does the donor marrow do?

Explanation:
After infusion, donor hematopoietic stem cells settle into the recipient’s bone marrow and begin producing new blood cells. This engraftment reconstitutes all blood lineages—red cells, white cells, and platelets—restoring oxygen transport, immune defense, and clotting. The marrow isn’t left dormant; its purpose is to reestablish the blood and immune systems. Infections can occur during the period of immunosuppression, but that isn’t the marrow’s action. Rejection is a possible complication, not the normal function.
