The CD3-CD56+CD16+ NK cells purified by the negative sorting method of MACS (magnetic microbeads activated cells sorting) were expanded with the different combinations of IL-2, SCF, IL-15 in SCGM (stem cell growth medium) supplemented with 10% human AB serum for 18 days. Cultures were fed with fresh medium and cytokines every 3 days.
