How are PBSCs obtained for transplantation?
A process called apheresis or leukapheresis is used to obtain peripheral blood stem cells for transplantation. For 4 or 5 days before apheresis, the patient may be given a medication to increase the number of stem cells released into the bloodstream. In apheresis, blood is removed through a central venous catheter (a flexible tube that is placed in a large vein in the neck or chest area). A needle placed in a large vein in an arm can also be used. The blood goes through a machine that removes the stem cells. The blood is then returned to the patient and the collected cells are stored. Apheresis typically takes 4 to 5 hours to complete. The collected cells may be treated with drugs to destroy any cancer cells that may be present (see question 13). The stem cells are then frozen until they are transplanted back to the patient. Return to top of page. • Are there any risks associated with donating bone marrow? Because only a small amount of bone marrow is removed, donating usually does not
The stem cells used in PBSCT come from the bloodstream. A process called apheresis or leukapheresis is used to obtain PBSCs for transplantation. For 4 or 5 days before apheresis, the donor may be given a medication to increase the number of stem cells released into the bloodstream. In apheresis, blood is removed through a large vein in the arm or a central venous catheter (a flexible tube that is placed in a large vein in the neck, chest, or groin area). The blood goes through a machine that removes the stem cells. The blood is then returned to the donor and the collected cells are stored. Apheresis typically takes 4 to 6 hours. The stem cells are then frozen until they are given to the recipient. • How are umbilical cord stem cells obtained for transplantation? Stem cells also may be retrieved from umbilical cord blood. For this to occur, the mother must contact a cord blood bank before the baby’s birth. The cord blood bank may request that she complete a questionnaire and give a smal
