Figure 2 Evolution of WT1 expression in PB (upper panels, triangles) and BM (lower panels, circles) in patients with low and stable WT1 levels (left panels) and patients with WT1 overexpression (right panels) after SCT.

Figure 3 Comparison of the results obtained from WT1 expression, chimerism (C), and FC for the follow up of MRD in PB (triangles) and BM (circles) from patients who relapsed after SCT. Positive results are identified by solid black symbols (triangles or circles), and negative results appear as hollow white symbols. Contiguous symbols (triangles and circles) represent PB and BM samples obtained on the same day. Vertical gray bars indicate the time of hematologic relapse. Patient numbers are identical to those in Tables 1 and 2 and Figure S1.
