Peripheral blood repopulation of total white blood cells, and CD3⁺, CD4⁺, and CD4⁺CD25⁺ T cells after BMT. (A) Repopulation of WBCs and T lymphocytes in PBLs. After aBMT, blood was drawn from the tail vein of the mice on a weekly basis and the WBC count was determined on a Coulter cell counter as well as the repopulation of the percentage of CD3⁺ T cells by FACS, shown (+ SEM). (B) Repopulation of CD4⁺ and CD4⁺CD25⁺ T cells in PBLs. FACS analysis on PBLs was performed on repopulation of the percentage of CD4⁺ and CD4⁺CD25⁺ T cells, shown (+ SEM).
