Percent donor chimerism after unrelated HCT.

Median percentages of donor peripheral blood CD56⁺ cells (NK-cells, ▵), CD3⁺ cells (T-lymphocytes; ○), and CD15⁺ cells (granulocytes; ●) are shown for the first 180 days after transplantation. The numbers of patients analyzed at days 28, 56, 84, and 180 were, respectively, 45, 40, 37, and 27 for T cells; 46, 40, 38, and 26 for granulocytes; and 27, 21, 19, and 15 for NK cells.
