To extend these studies to other SCLL models, we performed the same flow cytometric analysis in mice engrafted with the AML-like BCRF8C cells [43] expressing BCR-FGFR1 (Fig. 1C) and ZNF112 T-cell leukemia cells [4] expressing the ZMYM2-FGFR1 chimeric kinase (Fig. 1D). The gene discussed is BCR; the disease is T-cell leukemia.
