Early and late peripheral blood lineage analysis for total and prenatal- and postnatal-derived donor cell engraftment.

(A) Total donor cell lineage expression (prenatal + postnatal) at 8 and 24 weeks after DLI compared with B6 controls. (B) Hemoglobin analysis by HPLC documenting complete donor erythroid chimerism. (C) Lineage expression of prenatal- and postnatal- (DLI) derived cells expressed as a percentage of total prenatal and postnatal engraftment, respectively, at 8 and 24 weeks after DLI. *P < .05 prenatal donor versus B6 control. ***P < .001 postnatal donor versus B6-Ly5.2Cr control.
