A time course analysis was performed to identify the sites of
formation and timing of appearance of polytropic recombinant viruses
following infection of NIH/Swiss mice with the murine retrovirus SL3-3
murine leukemia virus (SL3) or with a weakly pathogenic mutant termed
SL3

Tissue Distribution and Timing of Appearance of Polytropic
Envelope Recombinants during Infection with SL3-3 Murine Leukemia
Virus or Its Weakly Pathogenic SL3
Myb5 Mutant
Myb5. The results indicated that (i) polytropic recombinant
viruses occur initially in the thymus of SL3-infected animals, (ii) the
timing of appearance of polytropic recombinants in bone marrow is not
consistent with their participation in the previously reported
formation of transplantable tumor-forming cells at 3 to 4 week
postinoculation, and (iii) the efficient generation of recombinant
virus is correlated with efficient tumor induction.
