KMT2A and acute myeloid leukemia: For in vivo confirmation, we generated murine AML by retroviral transduction of fetal liver cells from either Selplg–/– (CD162–/–) or WT mice with a bicistronic expression vector containing GFP and MLL-AF9 (11q23-rearrangement mimic) fusion oncogene as previously described (Barbier et al., 2020).
