Public cord blood banks operate similarly to publicly funded blood banks. Anyone can donate cord blood, provided it meets specific quality standards; otherwise, it is discarded. These banks utilize national registries to locate samples for potential matches.
Many patients need multiple cord blood units for treatment, as a single donation often isn't enough. Unlike bone marrow transplants, matching specific genetic markers isn't necessary for cord blood, simplifying the process of finding suitable donors.
However, around 60% to 80% of donations to public banks are rejected due to contamination or insufficient cell counts, and logistical challenges during transportation. Private banks typically lack strict quality controls, and using one's own cord blood offers less medical benefit. Public banks provide better matching options, making them more widely accepted in the medical community.
Establishing a public cord blood bank is costly because they do not charge storage fees, resulting in limited funding. Most cord blood transplants worldwide have been sourced from public banks. One study noted that only about 50 transplants involved private sources, mostly for family members, with most donors unaware of their need beforehand. This underscores the significance of public banking in stem cell treatments.
