Summary of PCR results on all patient samples post-transplantation. Samples were scored as negative if β-actin PCR of the sample gave a signal consistent with amplification of 500 ng of DNA. Samples were scored as positive only if both reagent and concurrently extracted normal PB controls were negative for the Neo signal. (○), Negative and (•), positive for vector used to transduce the BM, and (⊙), positive for the vector used to transduce the PB. MNC, mononuclear fraction of PB; GRAN, granulocyte fraction of PB.
