He was 1991 President of the International Society for Hematology and Stem Cell Research (ISEH), and was 2010 President, American Society of Hematology (ASH; only non-MD in the history of ASH to become President). His personal research involves mechanisms of regulation of hematopoiesis in context of stem cells/progenitor cells/cytokines.  He uses animal models to evaluate physiological activities of cytokines and cytokine combinations, and the influence of protein truncation by Dipeptidylpeptidase 4 (DPP4/CD26) on cytokine/chemokine activity. His studies on stem/progenitor cell kinetics of patients receiving various cytokines, have suggested means to better utilize these cytokines for efficacious use.  He evaluates alternative sources of transplantable hematopoietic stem and progenitor cells and was a discoverer of the utility of umbilical cord blood for this purpose.  His laboratory studies and first proof of principle cord blood bank in his laboratory set the stage for their clinical use, and he helped design the first clinical transplants that lead to their successful use. The first five of five, and seven of ten transplants of the more than 40,000 now performed were done with cord blood tested and frozen in his laboratory and hand-delivered to the transplant site. His group demonstrated that Extra Physiologic Oxygen Shock/Stress (EPHOSS) when cells are collected/processed in ambient air is detrimental to stem cells, effects mitigated by collecting/processing bone marrow and cord blood in hypoxia (3% O2) or with cyclosporine A in ambient air, for a more efficacious stem cell collection of potential clinical relevance (Cell, 2015). His laboratory efforts also led to the clinical studies he was involved in that established the hematopoietic stem and progenitor cell mobilizing capability of AMD3100, alone and in synergy with granulocyte colony stimulating factor.  Dr. Broxmeyer served on the Councils of ASH, ISEH, and the Society of Leukocyte Biology.  He served on numerous NIH and ACS study sections including on the NIH Hematology II Study Section twice for 5 years each time (and was Chairman for last 3 years of second term) and was Advisory Member for NHLBI of the NIH.  He has served three 5 year terms as a member of the Scholar, Special Fellow and Fellow grant review committee for the Leukemia Lymphoma Society. He is a long-time member of the advisory cord blood committee of the National Marrow Donor Program (NMDP), and served a two-year term on the HRSA/HHS committee on Blood Stem Cell Transplantation (2008-2010).  He was on the Board of Directors of the first cord blood banking company (Biocyte Corporation). He served as the chairman of the Board of Scientific Councilors, and on the External Advisory Board of the National Space Biomedical Research Institute (NSBRI/NASA). He has been on over 20 scientific Editorial Boards, including Blood, Experimental Hematology, the Journal of Immunology and Blood Cells, Molecules, and Diseases, and is currently on over 10 Editorial Boards,including the Journal of Experimental Medicine, and Stem Cells.  He is Senior Editor, Stem Cells and Development, and Consulting Editor for Journal of Clinical Investigation. His research has been continuously peer-review funded since 1976, and by the NIH since 1978 (usually with multiple NIH grants at the same time).
