Consistent with previous publications (19), the MCA-induced primary tumor cell lines contained three subpopulations of tumor-infiltrating NKp46+ cells: NK cells (CD49a-CD49b+), ILC1 (CD49a+CD49b-) and an intermediate population, int-ILC1, displaying characteristics of both populations (CD49a+CD49b+). Here, ITGA1 is linked to neoplasm.
