Shalapour et al. reported the same chromosomal translocations (TEL-AML1, E2A-PBX1, MLL rearrangement) that had been detected in leukemia cells in BM-derived MSCs (in a proportion varying between 10% and 54%) in 10 out of 10 ALL patients analyzed [23]. This evidence concerns the gene RUNX1 and acute lymphoblastic leukemia.
