For the next 5‐10 years or possibly longer, a high proportion of the Cord Blood Banks (CBB) inventory worldwide will be composed of unlicensed umbilical cord blood (UCB) units. While Food and Drug Administration (FDA)‐licensed units will be prioritized, it will always be possible that an unlicensed unit will have known attributes, making it a better source of cells for the given indication. Because of the wide variety of current and potential indications as a source of cells for hematopoietic reconstitution or other form of cellular therapy, it is critical that the investigators have access to unlicensed UCB units.
