The BMCs were apheresised from sibling donor or HLA-haplotype-matched donor, then the T cells were selected and transfected with lentivirus to generate CARs. At last, the qualified CAR-T cells were infused into relapse subjects to kill the leukemia cells. CAR chimeric antigen receptor, BMC blood mononuclear cells.
