Also, cord blood storage is a new enough technology, that it is not clear how long the blood can remain frozen and still be effective. Therefore, if an adult develops a treatable disease, even if his own cord blood was banked, the quantity will be insufficient to produce a cure. Although research is being done to try to multiply cord cells in the laboratory in quantities great enough to treat an adult, results have not been successful. The cord blood cells that some people bank after the birth of a child are a form of adult blood-forming stem cells.

If this is an option for you, before your baby's birth, ask your doctor about how to make arrangements to donate umbilical cord blood to a cord blood bank. The cord blood can be frozen and stored until it's used in a cord blood transplant. Cord blood contains hematopoietic progenitor. Umbilical cord blood is the blood left in the umbilical cord after a baby's birth. Most UCB transplants in adults are performed using 2 UCB units 29,30. Minimum cell dose for single unit UCB is 2 × 10 5 CD34 + cells/kg of recipient weight. In addition, the quantity of cord blood that can be collected is only enough to treat a child. Cord blood is the blood contained in the placental blood vessels and umbilical cord, which connects an unborn baby to the mother's womb. Umbilical cord blood (UCB) transplant is performed using the collected blood (approximately 50100 mL) from the umbilical cord and placenta. However, if the disease is caused by a genetic defect, (e.g., sickle cell and other anemias) the child's own stem cells will be useless, because they will contain the same genetic defect. It can happen after any donor transplant, including cord blood.
Private cord cell banks sell their services as a type of "insurance." In case the child develops a treatable disease, the child's own stem cells will be a perfect match. Although the list of diseases treated with umbilical cord stem cells is impressive and growing, controversy exists about whether parents should pay private cord cell banks to preserve their newborn's blood.
