Mature thymocytes fail to resolve into CD4 and CD8 SP populations in Ets1-deficient mice. (A and B) Thymocytes from Ets1+/+ (top) or Ets1−/− (bottom) mice were assessed by flow cytometry for surface expression of CD4, CD8, CD24, and TCRβ. Two-parameter contour plots are shown on all live cells for expression of CD4 and CD8 (A) or of CD24 and TCRβ (B, left); TCRhi CD24lo mature thymocytes are analyzed for CD4 and CD8 expression (B, right). Numbers next to boxes indicate the percentage of cells within that box. Note that the level of CD24 expression was not affected by Ets1 disruption by itself. Data are from more than three experiments. (C) Bar graphs (mean ± SEM; n = 5 for each genotype) represent the absolute numbers of thymocytes within each mature (TCRβhi CD24lo) subset.
