The Natural Killer Cell Line (KIL) preserves most properties of the normal immature Natural Killer (NK) cells. As such, KIL provides a valuable model system for NK cell research.
Natural killer cells, large granular lymphocytes (LGL) that develop in the bone marrow, are a critical component of the innate immune system that also play a role in the body’s response to cancer and viral infections. NK cells function by releasing granzymes such as perforin to mediate cytotoxicity through apoptosis or cell lysis.

Growth Factor Responses of Natural Killer Cell Line (KIL)
(A) Survival of KIL in response to single cytokines. KIL cells were washed with phosphate-buffered saline and exposed to various cytokines (IL-7, SCF, Flt3L) at the indicated concentrations. Viable cells were counted after 4 days and expressed as percent of the maximal response. Each point represents the mean of triplicates. (B) SCF synergized with IL-7 to stimulate the proliferation of KIL. Each culture was started with 5x105 washed KIL cells. Cell numbers were determined on days 2, 4, and 6. Each point represents the mean of triplicates.
