If your child is having an autologous transplant, his or her cells will first be collected from the peripheral (circulating) blood or from the bone marrow. These cells will be cryopreserved (frozen).
Before the transplant, your child will first be tested for infectious diseases. This testing is standard for everyone donating blood products. The primary physician or a transplant physician must also check your child to determine whether he or she is medically able to have the transplant.
Peripheral blood stem cells are usually treated with chemotherapy and the growth factor granulocyte colony-stimulating factor (G-CSF). Sometimes, patients who do not need more chemotherapy may have stem cells collected after receiving only the growth factor.
Alternatively, a bone marrow harvest may be done at any time after the white blood cell counts have reached normal levels. Before stem cells are collected, the patients meet with a stem cell transplant physician to review the procedure for stem cell collection.
