Abstract:
Natural killer (NK) cells are lymphocytes that play an important role at clearing virally infected or cancer cells. Their potential and role in cancer immunotherapy have generated great interest, given the promising results of NK cell adoptive transfer clinical trials. The remaining challenge to bring emerging NK cell immunotherapies to the clinic is to enhance the production of large numbers of functionally competent NK cells ex vivo. Here, we describe two in vitro NK cell development assays using hematopoietic progenitor cells (HPCs), one for human NK cells and one for mouse NK cells. These protocols describe two robust methods that can be utilized for investigation of NK cell development and function.
