The FT538 iPSC‐NKs robustly induced apoptosis in an E:T ratio‐dependent manner in primary AML cells from all 11 patient samples (Figure S2), including primary AML cells derived from the four patients with FLT3 mutations and three with TP53 mutations (Figure 2, Figure S2). This evidence concerns the gene FLT3 and acute myeloid leukemia.
