Stem cell transplantation is a potential cure for sickle cell disease. Stem cells can be found in bone marrow. Bone marrow is
the substance in the center of your bones that produces red blood cells. A
sickle cell disease has bone marrow that produces red
blood cells with defective hemoglobin S. But if that bone marrow is replaced
with healthy bone marrow, a person's body may start to produce normal
Stem cell transplants require bone
marrow from another person (donor). This is called an allogeneic stem cell transplant.
Before the transplant, bone marrow stem cells are
taken from someone who has closely matching bone marrow, usually a healthy
brother or sister. The child who has sickle cell disease is then treated with
drugs that destroy his or her bone marrow cells. After that, the donated bone
marrow stem cells are injected into a vein.
After the process is
complete, the donor's bone marrow begins to replace the recipient's bone
marrow. These new cells restore the
immune system and make normal red blood cells.
Until recently this treatment was mostly done for children. This is because the risk of problems increases with a person's age. But new methods of doing a stem cell transplant are making it possible to successfully treat adults.

During recovery, doctors watch closely for signs
that the immune system is rejecting the new bone marrow and for signs of
infection. If a problem occurs, recovery can take longer or the transplant may
Stem cell transplants offer a
potential cure for a child's sickle cell disease. They are usually considered
only for children younger than 16 who have:footnote 1
The risks of stem cell transplant become greater as a
person gets older and/or develops damage to major organs. For these reasons, a
bone marrow transplant is not a treatment option for most adults who have
sickle cell disease. But research on bone marrow transplants in adults is ongoing.
If successful, a bone marrow
transplant can cure sickle cell disease. This treatment has been successful in about 85 out of 100 children who had transplants.footnote 1, footnote 2 But the risk of dying after a transplant is about 5%.footnote 3
