Abstract
Interleukin-2 (IL-2)-induced generation of non-major histocompatibility complex (MHC)-restricted killer cells among human cord blood lymphocytes (CBL) was investigated. After 1 week in culture with recombinant (r)IL-2 and human serum (HuSer), the cytotoxicity of CBL against K562 and COLO cells greatly exceeded the cytotoxicity of cultured adult peripheral blood lymphocytes. Culturing of CBL with rIL-2 and HuSer led to preferable generation of CD56+ cells. After 1 month in culture, the number and frequency of CD56+ cells had increased by more than 50 and nine times, respectively. The generation of CD56+ cells in CBL cultures may at least partially be explained by their comparatively strong expression of the IL-2 receptor (IL-2R) beta-chain (p75).
