Figure 1.

Post-UCBT Bone marrow engraftment analysis. Shown are capillary electropherograms of PCR amplification products for a single chromosome 7 short tandem repeat marker (D7S820). Pretransplant samples are shown on the left. A 9-month posttransplant peripheral blood sample is shown on the right. Whole, CD3+, and CD15+ denote an unfractionated sample, a CD3 selected whole blood fraction (T-cells), and a CD15 selected whole blood fraction (myeloid cells), respectively. Below each peak, the number of repeats and integrated fluorescence intensity are provided.
