To further investigate the potential contributions of other neutrophil subpopulations to the antitumor response, we also administered Sell(lo) neutrophils, by adoptive transfer alone or with OT‐I CD8 T cells to mice bearing MOC2‐OVA tumors and no significant synergistic tumor growth inhibition was observed in combination groups (Figure S6g–i, Supporting Information). Here, SELL is linked to neoplasm.
