After a single step of magnetic CD3+ T-cell depletion, PBMCs are stimulated and expanded with irradiated autologous cells in the presence of OKT3 and IL-2, resulting in a highly pure population of functional CD3−CD16+CD56+ NK cells that lack cytotoxicity against allogeneic non-tumor cells (83) (Table 1). Here, NCAM1 is linked to neoplasm.
