We here report the initiation of hematopoietic recovery in congenitally
hypoplastic S1/S1d mice by the cytotoxic ablation of cells bearing the
natural killer (NK) phenotype (NK 1.1+). The most striking finding was the
early several-fold increase in the cycling fraction of stem and progenitor
cells (with the exception of progenitors committed to megakaryocytopoiesis)
in the anti-NK 1.1+ antibody-treated group. This increase resulted in an
early, complete restoration of total marrow cellularity to the normal (+/+)
littermate level. Our data suggest that NK 1.1+ cells exert functions
critical to the negative control of hematopoietic cell proliferation in
S1/S1d mice.
