Figure 2. TCF-1-deficient mice have reduced proportion and number of NKT cells.

Flow cytometry of thymocytes showing percent of gated CD1d-tetramer+ TCRβ+ NKT cells from wild-type (WT) and TCF-1 knock-out (KO) mice (A) and from WT, Vα14-Tg and TCF-1-KO Vα14-Tg mice (B). Representative dot plots and graphs with cell percentages and cell numbers from 4–6 mice per group are shown (mean and s.e.m.). Numbers over dot plots refer to total thymocyte cell numbers; *P<.05; **, P<.01; ***, P<.001.
