CR3-sufficient NK cells (from WT mice) and CR3-deficient NK cells (from CD11b−/− mice) were similarly grafted in tumor bearing E4bp4−/− mice 24 h after intravenous injection of the NK cells (Figure S5 in Supplementary Material), which suggest that CR3-deficient NK cells have no apparent defect in migration in this model. Here, CRIPTO3 is linked to neoplasm.
