Fig 4. At weeks 1, 2, 4, 8, and 12 after BMT, leukocytes isolated from the spleen and bone marrow were stained with anti-TCRβ,-K^b, and-D^d monoclonal antibodies (n = 4 at each time point).

The bars show the ratio and absolute numbers of B6-orginated TCRβ⁺ T cells (■) and Balb/c-originated TCRβ⁺ T cells (□). Data are shown as the mean ± SD. p values compared to donor-derived cells one week after BMT. ***, p ≤ 0.0001 or p ≤ 0.001; **, p ≤ 0.01; and *, p ≤ 0.05.
