Harvesting bone marrow stem cells
The harvest of bone marrow stem cells is very similar to a bone marrow aspiration. The donor will receive anesthesia so no pain will be felt, and the donor will have no memory of the procedure.
Peripheral blood stem cell donation
Stem cell donors are sometimes needed for patients who require a stem cell transplant. The donated stem cells can come from the bone marrow or from the peripheral blood. Peripheral blood is blood in the veins.
