NMDP collaborated with researchers at the University of Minnesota to find an association between the poverty of donors for stem cell transplants and the survival outcomes of recipients…. “This study suggests that there is a biological effect of poverty,” said Dr. Jeff Auletta, a senior vice president of health equity for the National Marrow Donor Program. Also known as NMDP, the Minneapolis-based agency matches patients worldwide to the most suitable donor bone marrow and stem cells for transplants.
