To compare the engraftment levels in the two strains, 1 × 105 Lin- CD34+ cells derived from 3 CB samples were transplanted into 5 NOD/SCID/IL2rγnull mice and 4 NOD/SCID/β2mnull mice. At 3 months after transplantation, BM, spleen, and peripheral blood (PB) of the recipient mice were analyzed for the engraftment of human cells. Data show percentages of human CD45+ cells in each tissue.
