Detection of SF-MDR provirus in cells obtained from chimeric NOD/SCID mice.
(A) PCR analysis of the mononuclear cell (MNC) fraction and the granulocyte (polymorphonuclear; PMN) fractions of BM recovered from 11 mice (NOD/SCID set 7) engrafted with mock-transduced (1 and 2) orMDR1-transduced (3-11) CD34+ PBPC. (B) Detection of the SF-MDR proviral genome in individual colonies derived from 2 chimeric mice (NOD/SCID sets 2 and 8) engrafted with Transwell-transduced CD34+ PBPC. (C) Detection of the SF-MDR proviral genome in individual colonies derived from 2 chimeric mice (NOD/SCID set 10) engrafted with supernatant-transduced CD34+ PBPC. M denotes molecular-weight size marker; Nc, no-template PCR control; and Pc, SF-MDR producer cells diluted 10−5-fold in provirus-negative HL-60 cells.
