Expression of NK cell markers in the uNK and pNK population from non-pregnant and pregnant mice.

<p>Expression of NK1.1, DX5, DBA and NKp46 were determined on CD3^-CD122⁺ cells isolated from the uteri of non-pregnant (A) syngeneically mated pregnant (B) and allogeneically mated (C) pregnant CBA mice. Expression of NK1.1, DX5, DBA and NKp46 on CD3^-CD122⁺ cells from spleen of non-pregnant CBA mouse (D), syngeneically mated (E) and allogeneically mated (F) pregnant CBA mouse. Red-boxed areas denote uNK populations positive for NK1.1 and DBA in allogeneically mated pregnant CBA mouse (C) and DBA positive uNK population in syngeneically mated pregnant CBA mouse (B). These positive populations are absent in the splenic NK cell population in the same mouse. Data is representative of at least 3 experiments.
