Data about the numbers of potential marrow donors and donated umbilical cord blood units listed on the donor registry of the C.W. Bill Young Cell Transplantation Program (CWBYCTP), including the National Cord Blood Inventory, are reported annually.
One of the CWBYCTP goal is to increase the numbers of marrow donors and cord blood units on the CWBYCTP donor registry. The program seeks to help more people who have difficulty finding a matching donor by placing special emphasis on registering marrow donors and collecting cord blood units from these genetically varied communities:
- American Indian or Alaska Native
- Asian
- Black or African American
- Hispanic or Latino
- Native Hawaiian or Other Pacific Islander
The growth in numbers of marrow donors and cord blood units, plus the genetic variability of the registry, are improving all patients' chances of finding the match they need.
The U.S. registry contains more than 246,500 available cord blood units. This total includes more than 122,500 units from the National Cord Blood Inventory (NCBI), with 3,700 NCBI units added in 2024.
