• What is a Stem Cell Transplant (Bone Marrow Transplant)?

    A stem cell transplant (also called bone marrow transplant) is the infusion of healthy stem cells into the body to stimulate new bone marrow growth. Stem cells are vital to a person’s ability to fight infection. Stem cell transplants are performed on children whose stem cells have been damaged by disease or invasive treatments for cancer such as chemotherapy and or radiation therapy. There are two types of stem cell transplant:

    • Autologous transplants, in which the patient’s own stem cells are collected, stored at a special laboratory and re-introduced into the patient’s system intravenously.
    • Allogeneic transplants, in which stem cells are collected from a tissue-matched donor (a sibling, an unrelated donor, or umbilical cord blood) and delivered intravenously. Learn how we can help find a stem cell donor.

    We perform both autologous and allogeneic stem cell transplants to treat a range of cancerous and non-cancerous conditions. Learn about all of the childhood conditions treated by stem cell transplants.

    The Stem Cell Transplant Process

    All children undergoing a stem cell transplant are given high-dose chemotherapy to make room in their bone marrow for the new stem cells, suppress their immune system to prevent graft rejection, and destroy cancer cells in their body. After this conditioning regimen, they are given a few days’ rest before their transplant.

    Like a blood transfusion, stem cells are given to a child through an intravenous catheter. Children are awake through this painless process. It generally takes two to six weeks for the engraftment to “take” and for the stem cells to multiply and make new blood cells.

    Minor side effects, such as fever, chills and shortness of breath, can accompany the infusion of new stem cells. More significant complications, including graft rejection and graft-versus-host disease (a condition in which the donor’s immune cells attack the patient’s body), can occur following the transplant.
