Quantification of nucleated red blood cells in allogeneic marrow graft and impact of processing on recovery

BACKGROUND: In allogeneic bone marrow transplantation (BMT), a higher nucleated and CD34+ cell dose has been reported to improve various outcomes. Other cell types, such as lymphocyte subsets, also influenced BMT results. While nucleated red blood cells (NRBCs) represent a subset of bone marrow (BM) cell subpopulation, the question of their quantification in BM grafts and the impact of BM processing on their recovery has not been addressed.
