Cord blood banking: a historical perspective.

摘要

Umbilical cord blood (UCB) contains stem and progenitor cells capable of restoring haematopoietic and immunological function in vivo. UCB is currently used as an alternative source of haematopoietic stem cells for transplantation in patients suffering from haematological malignancies, bone marrow failures and inherited metabolic disorders. In order to facilitate transplantation, large repositories of frozen cord blood units (CBUs) from altruistic donations have been established in many parts of the world and to date there are more than 300,000 units stored worldwide. These products have been banked under stringent quality conditions, in order to ensure their safety and efficacy. The development and evolution of the policies and procedures currently in use in cord blood banking have been largely influenced by the clinical results of cord blood transplantation. This review aims to provide a historical overview of the various developments in the field of cord blood banking from its inception, highlighting the relevant aspects in their collection, banking and release that are known to influence the clinical outcome of these transplants.
