Ethical and Regulatory Considerations in the Clinical Translation of Pluripotent Stem Cell‐Derived <scp>NK</scp> Cell Therapies

Advancements in the generation of human pluripotent stem cell-derived natural killer (PSC-NK) cells have attracted considerable attention within the biomedical research community, offering a promising off-the-shelf technique for universal immune therapy. However, this technique is associated with certain ethical, safety, and regulatory challenges, including ensuring genomic stability, preventing contamination and adhering to rigorous ethical standards for cell sourcing and obtaining informed consent. Addressing these challenges would require robust quality control, transparent data-sharing practices, and cross-border collaboration to ensure alignment with ethical and scientific standards. Future development must therefore focus on patient safety, data privacy and equitable access within a comprehensive ethical framework. These measures are crucial for maintaining public trust in and enabling the responsible clinical integration of PSC-NK therapies, thereby supporting their advancement while maintaining a balance between innovation and societal and ethical considerations.
