NCR1 and acute myeloid leukemia: We also injected equal numbers of Ncr1+/+ ILC1s and Ncr1gfp/gfp ILC1s separately into Ncr1gfp/gfp mice that had been transplanted with C1498-Luc AML cells to rescue the dramatic decrease in ILC1s observed in Ncr1gfp/gfp mice, with no adoptive transfer of ILC1s used as a control.
