What are other sources of stem
cells?
Bone Marrow - Stem cells can be harvested
from the bone marrow. The harvesting procedure is invasive, time consuming and painful for the donor. Perhaps the
biggest hurdle in bone marrow stem cell transplantation is finding the perfect match. This has proven to be quite
difficult and sometimes impossible. This is a special problem among minority groups where the number of donors is
significantly lower.
Peripheral Blood - Stem
cells can also be harvested from the peripheral (circulating) blood. However, for some patients, their stem cells are
contaminated or damaged by the underlying disease process. Using these stem cells would not be an option. On the
other hand, umbilical cord blood provides a pure uncontaminated source of stem cells.
Cord Blood - Like bone marrow, cord blood is rich in stem cells. There are, however, significant differences which
exist between umbilical cord blood and bone marrow.
- Because cord blood is from a newborn and is unexposed to most disease, transplant complications are less
frequent.
- The cells from your child’s umbilical cord are a perfect match for your child, minimizing the chance for
graft-versus-host-disease (rejection).
- Harvesting umbilical cord blood stem cells is easy and painless, and takes only about ten
minutes.
