Cord blood bank
A cord blood bank is a facility which stores umbilical cord blood for future use. Both private and public cord blood banks have developed in response to the potential for cord blood in treating diseases of the blood and immune systems. Public cord blood banks accept donations to be used for anyone in need, and as such function like public blood banks. Traditionally, public cord blood banking has been more widely accepted by the medical community. Private cord blood banks store cord blood solely for potential use by the donor or donor's family. Private banks typically charge around $2,000 for the collection and around $200 a year for storage.The policy of the American Academy of Pediatrics states that ""private storage of cord blood as 'biological insurance' is unwise"" unless there is a family member with a current or potential need to undergo a stem cell transplantation. The American Academy of Pediatrics also notes that the odds of using one's own cord blood is 1 in 200,000 while the Institute of Medicine says that only 14 such procedures have ever been performed. Private storage of one's own cord blood is unlawful in Italy and France, and it is also discouraged in some other European countries. The American Medical Association states ""Private banking should be considered in the unusual circumstance when there exists a family predisposition to a condition in which umbilical cord stem cells are therapeutically indicated. However, because of its cost, limited likelihood of use, and inaccessibility to others, private banking should not be recommended to low-risk families."" The American Society for Blood and Marrow Transplantation and the American Congress of Obstetricians and Gynecologists also encourage public cord banking and discourage private cord blood banking. Nearly all cord blood transfusions come from public banks, rather than private banks, partly because most treatable conditions can't use one's own cord blood.Cord blood contains hematopoietic stem cells (which can differentiate only into blood cells), and should not be confused with embryonic stem cells or pluripotent stem cells, which can differentiate into any cell in the body. Cord blood stem cells are blood cell progenitors which can form red blood cells, white blood cells, and platelets. This is why cord blood cells are currently used to treat blood and immune system related genetic diseases, cancers, and blood disorders. On the possibility that cord blood stem cells could be used for other purposes, the World Marrow Donor Association and European Group on Ethics in Science and New Technologies states ""The possibility of using one’s own cord blood stem cells for regenerative medicine is currently purely hypothetical....It is therefore highly hypothetical that cord blood cells kept for autologous use will be of any value in the future” and “the legitimacy of commercial cord blood banks for autologous use should be questioned as they sell a service which has presently no real use regarding therapeutic options.”
