The National Marrow Donor Program facilitates cellular transplants for patients suffering from cancer-related diseases through its registry of 11 million marrow donors and 290,000 umbilical cord blood units. The program’s DNA halpotype analysis uses mathematical models and algorithms to predict match probability. A commitment to creating a genetically diverse, secure registry and providing related technical expertise has allowed the program to increase match quality, the number of transplants, and overall access to donors and cord blood units, reduce times to transplant, and advance medical research. The program has facilitated more than 30,000 transplants since 1987, including 3,700 in 2007 alone, which is a 15.6 percent increase over 2006.
