Furthermore, the Haplo procedure may be associated with enhanced anti-leukemic efficacy as was recently nicely proved by Professor Huang Xia June in a mice model which carried the human AML-ETO or MLL-AF9 fusion gene showing that cytotoxic T lymphocytes from the haploSCT group had higher cytotoxicity than those from the MSD group [38]. This evidence concerns the gene KMT2A and acute myeloid leukemia.
