Graphic representation of hematologic parameters and engraftment status at selected times after bone marrow transplantation.

Blood components (absolute lymphocyte count [ALC], absolute neutrophil count [ANC], platelets) and hemoglobin values are shown in the lower panel. Percentage donor cells analyzed by cytogenetics in the recipient after transplantation are shown in the top panel. A specific 1qh+ polymorphism was detected in the recipient before BMT. At 1 and 3 months after BMT, analysis of PHA-stimulated PBLs demonstrated mixed chimerism. Full donor engraftment was found at 6 months, and all subsequent findings of PBLs and BM (at 1 and 8 years) have remained 100% of donor origin.
