The London Cord Blood Bank

Cord blood (CB) contains a sufficient number of haemopoietic progenitor cells and can be used as an alternative to bone marrow transplantation. To date, a number of transplants using cord blood-derived stem cells from HLA-identical siblings and unrelated donors have been successfully performed. However, only approximately 30% of patients have an HLA-identical sibling while the rest are reliant on finding an HLA-compatible unrelated donor. This is particularly difficult for patients from ethnic minorities since the majority of unrelated bone marrow donor volunteers are from Caucasoid ancestry. The London Cord Blood Bank was established to provide an additional source of stem cells for all patients requiring bone marrow transplantation.
