These primary AMLs are designated hereafter by the number of the mouse that received transplant, genotype of the donor HSPCs, and virus (eg, 2232 Mntfl/flCreERT2/MLL::AF9 indicates AML that developed in mouse 2232 transplanted with Mntfl/flCreERT2 fetal liver cells infected with MLL::AF9/GFP virus). Here, MLLT3 is linked to acute myeloid leukemia.
