Expanding Cancer Cell Therapy with Stem Cell-Derived NK Cells

A streamlined protocol for generating iNK cells from PSC spheroids

Share

Natural killer (NK) cells are cytotoxic, innate, lymphoid immune cells that can kill malignant cells without the need for HLA matching, making them appealing in the ever-growing cancer cell therapy field. However, the large number of NK cells needed for therapeutically relevant applications underscores the need for improved cell therapy manufacturing scalability. Researchers are exploring pluripotent stem cells (PSCs) as a source of allogeneic NK cells, or invariant NK (iNK) cells, but typical PSC-to-iNK cell differentiation protocols are inconsistent and lack scalability. Using a suspension medium with 3D PSC expansion capabilities, scientists developed a new easy-to-scale protocol to differentiate and expand PSC-derived iNK cells.

Download this protocol from Thermo Fisher Scientific to discover the steps involved in PSC-to-iNK differentiation and expansion with Gibco™ CTS™ StemScale™ PSC Suspension Medium, including

  • PSC-to-induced hematopoietic progenitor cell (iHPC) differentiation
  • iHPC-to-iNK cell differentiation
  • iNK expansion

Why Do We Feel Butterflies in the Stomach?

These fluttering sensations are the brain’s reaction to certain emotions, which can be amplified or soothed by the gut’s own “bugs".
