Kaplan-Meier–style survival curves for lethally irradiated recipients receiving BM cells transduced with the indicated bcr/abl cDNA.

The number of analyzed mice (N) is shown in the figure. Mice receiving MigR1-transduced BM cells were healthy for more than 300 days (not shown). Of the surviving Δ(1-63) bcr/abl mice, 2 mice have been followed for longer than 25 weeks (30 and 40 weeks, respectively).
