MINNEAPOLIS, July 9, 2025 – NMDP SM , a global nonprofit leader in cell therapy, and its collaborative research program, CIBMTR® (Center for International Blood and Marrow Transplant Research®), have released revised donor and cord blood selection guidelines to enhance transplant outcomes for patients. Published in peer-reviewed Journal of Transplantation and Cellular Therapy , the updated guidelines usher in a new era of clinical clarity and standardization around donor choice in hematopoietic cell transplantation (HCT) – enabling transplant centers and researchers access to the latest evidence-based methods for selecting suitable donors for patients who have the 75+ blood cancers and disorders for which transplant is a potential curative therapy.
“Donor selection is a highly specialized and individualized process that must account for a multitude of clinical factors, and health care providers and transplant center staff rely on published guidance around shared standards to inform complex, clinical decision-making,” Antonio Martin Jimenez Jimenez, MD, first author and associate professor of medicine, Sylvester Comprehensive Cancer Center, part of the University of Miami Miller School of Medicine, said. “Transplantation science is meeting previously unmet needs across a broader range of patients than ever before, demonstrating the transformative impact of evidenced-based care.”
Developed by a multidisciplinary panel of experts, the guidelines mark the first comprehensive update to the NMDP/CIBMTR guidelines since 2019 and incorporate the latest evidence-based research on donor type, human leukocyte antigen (HLA) matching and non-HLA factors that enhance patient outcomes.
Highlights of the updated guidelines include:
“Selecting a donor is both a data-driven and emotionally charged decision, and it remains one of the most critical determinants of patient outcomes,” Steven Devine, MD, chief medical officer, NMDP, senior scientific director, CIBMTR, and co-author of the study, added. “These guidelines shed new light on the rapidly-evolving transplant landscape and empower health care professionals to move faster and focus on giving patients the best chance at survival. They also improve operational efficiency for transplant centers and support care teams with guidance that reflects evidence-based science and compassion.”
For help assessing the availability of 8/8 matched donors and alternative source options, NMDP offers free consultations with its search strategy experts and an online search prognosis calculator .
