Msr1 does not affect BCR-ABL–induced lymphoid leukemia. (A) Kaplan-Meier survival curves for recipients of BCR-ABL–transduced bone marrow cells from WT (n = 10) or Msr1^−/− (n = 8) donor mice. Both groups of mice developed and died of ALL. (B-C) FACS analysis showed similar numbers of GFP⁺B220⁺ cells in peripheral blood of recipients of BCR-ABL–transduced bone marrow cells from WT (n = 5) or Msr1^−/− (n = 5) donor mice. (D) Spleen masses of recipients of BCR-ABL–transduced bone marrow cells from Msr1^−/−(n = 9) donor mice is similar to WT (n = 4) donor mice.
