Associations between transplant variables and chimerism. (A) Kinetics of T-cell engraftment according to underlying diseases. (B) Kinetics of T-cell engraftment according to chemotherapy history. There were 17 patients who did not receive chemotherapy or received agents such as chlorambucil, hydroxyurea, imatinib mesylate, or immunomodulators who were termed “no prior chemotherapy,” while those who received more intensive chemotherapy (n = 103) were termed “prior chemotherapy.” (C) Comparison of kinetics of T-cell engraftment in recipients of HLA-matched related or unrelated G-PBMCs.
