NCAM1 and neoplasm: We then compared the cytotoxicity of selected CD3−CD56+ NK cells with that of the same number of CD3−CD56+ cells in microbead-selected CD56+ cells and found that the microbead-selected CD56+ cells exhibited significantly higher cytotoxicity than the selected CD3−CD56+ NK (Figure S2b), which suggested that CD3+CD56+ NKT cells also contribute anti-tumor activity.
