Effect of depletion of Ly49G2⁺ or Ly49C/I⁺ NK subsets in C.B-17 SCID (H2^d) mice 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 7.5 × 10⁶ allogeneic BMCs. On the eighth day a soft agar colony assay was done to assess hematopoietic progenitor content in the spleens (mean ± SD). *Values significantly (P < .0001) lower than mice receiving NRS.
