Effect of depletion of Ly49G2⁺ or Ly49C/I⁺ NK subsets in H2^bxd F₁mice on the engraftment of H2^b allografts.

Mice were given various mAb treatments or NRS 2 days before irradiation. Irradiated mice (4 mice/group) received either 0.5 × 10⁶ (A) or 20 × 10⁶ parental-strain H2^b BMCs (B). On the eighth day a soft agar colony assay was done to assess hematopoietic progenitor content in the spleens (mean ± SD). *Values significantly (P < .006) greater than mice receiving NRS in experiment A; **values significantly (P < .0004) greater than mice receiving NRS in experiment A; ***values significantly (P < .006) lower than mice receiving NRS in experiment B.
