Flt3L treatment of bone marrow donors increases graft plasmacytoid dendritic cell content and improves allogeneic transplant outcomes

Higher numbers of donor plasmacytoid dendritic cells (pDC) increased survival and reduced graft-versus-host disease (GvHD) in human recipients of unrelated donor bone marrow (BM), but not G-CSF peripheral blood grafts. In murine models, we have shown that donor BM pDC increase survival and decrease GvHD compared to G-CSF-mobilized pDC. To increase the content of pDC in BM grafts we studied the effect of FMS-like tyrosine kinase 3 ligand (Flt3L) treatment of murine BM donors on transplant outcomes.
