Therefore, we compared the numbers of total NK (lin−CD122+), NK cell precursors (NKP, lin−CD122+NKp46−CD49b−), the more differentiated immature NK (iNK, lin−CD122+NKp46+CD49b−), and mature NK (mNK, lin−CD122+NKp46+CD49b+) cells in bone marrows of normal, SRα-tTA-MYCON (lymphoma), and SRα-tTA-MYCOFF (regressed lymphoma) mice. Here, NCR1 is linked to lymphoma.
