Spleen cells of normal specific-pathogen-free N, P, and 15 × 7 chickens were cytotoxic in vitro for target cells of Marek’s disease lymphoma line MSB-1. The natural killer (NK) cell activity, best expressed in chickens over 7 weeks old, varied among several genetic lines of chickens tested. The NK cells were thermolabile, and incubation of the cells at 37° C for 30–60 minutes resulted in substantial loss of cytotoxicity. The specificity of NK effector cells was directed against common antigen(s) on tumor cell lines of diverse origin but not on normal adult or embryonic cells.
