This study looks at using unlicensed cryopreserved cord blood units (CBUs) for patients with blood cancers and other conditions. Cord blood is collected from the umbilical cord after a baby is born and can be used for transplants to help treat certain diseases. In this study, doctors will use CBUs that are not approved by the Food and Drug Administration (FDA). They want to find out how well these CBUs work by checking if the patients recover certain blood cells called neutrophils. They will also look at how often infections happen, if there are reactions to the infusion, and how many patients survive for a year after the transplant.

• The study involves pediatric and adult patients of any age.
• Participants must have a disorder of the blood system and provide consent.
• This is a multi-center study, meaning it takes place at several hospitals in the U.S.
