Such commercial banking of cord blood has important implications for National Health Service maternity units. The debate on whether commercial cord blood banking should be encouraged has mostly been limited to the scientific merits, but risk management, medicolegal, and ethical issues also need considering.
Growth of blood banking
Umbilical cord blood is rich in stem cells that can be used to treat patients with abnormal haematopoietic cell lines, childhood leukaemia, or metabolic diseases.1 Bone marrow is used for this purpose, but cord blood is cheaper and easier to obtain and less likely to trigger a harmful immune response or rejection in the recipient.2
For these reasons interest has been growing in banking cord blood. The collected sample is commercially processed and stored for possible autologous transfusion in the future, a practice commonly referred to as biological insurance.
Media hype about the potential of stem cell transplantation3 and marketing by the commercial cord blood banks are likely to increase requests for blood collection at delivery. These banks advertise on the internet, distribute literature in antenatal clinics, and directly approach doctors and midwives.
A booklet distributed by one of the commercial banks tells potential clients that, “The cure for many life threatening diseases is dependent on the transplantation of stem cells.”4 It speaks of “unimaginable possibilities” and states: “Potentially [stem cell] research should provide answers to curing diseases such as diabetes, breast cancer, ovarian or testicular cancer, melanoma, …
