Similar to NK cells from other sources, iPSC‐derived NK cells exhibit killing capacity against tumor cells through the secretion of cytolytic enzymes, secretion of proinflammatory cytokines, such as perforins, granzymes, IFN‐γ and TNFα, or direct cell contact‐mediated apoptosis through TRAIL and Fas–FasL interaction.95 This evidence concerns the gene IFNG and neoplasm.
