At weeks 1, 2, 4, and 12 after BMT, leukocytes isolated from the thymus were stained with anti-TCRβ,-CD4,-CD8,-K^b, and-D^d monoclonal antibodies (<i>n</i> = 4 at each time point).

<p>(A) The numbers in the dot plot show the percentage of B6-originated T cells among the total leukocytes. (B) The bars show the ratio and absolute numbers of B6-orginated TCRβ⁺ T cells (■) and Balb/c-originated TCRβ⁺ T cells (□). (C) The bars show the ratio and absolute numbers of B6(Balb/c)-originated TCRβ⁺CD4⁺ and TCRβ⁺CD8⁺ T cells. Data are shown as the mean ± SD. p values compared to donor-derived cells one week after BMT. **, p ≤ 0.01, and *, p ≤ 0.05.
