CD3ϵ deficiency blocks the TAL1xLMO1-induced leukemogenesis. Comparison of tumor susceptibility between TAL1xLMO1 mice (n = 25) and (A) TLMpTαko mice (n = 24), (B) LMO1pTαko mice (n = 10), (C) TLMCD3ϵko mice (n = 21), and (D) LMO1CD3ϵko mice (n = 21). Kaplan-Meier representations are shown. Survival rates are compared by the log-rank test.
