Expression of TfR1, TfR2-α, and TfR2-βmessenger RNA was analyzed by semiquantitative reverse-transcriptase polymerase chain reaction and shown as a percentage of the level detected in K562 cells. As reference, the mean ± SD of expression levels of nonmalignant marrow samples are shown in the bottom row (control).

Samples that had high levels of expression ofTfR2 mRNA (greater than 60% K562).
