RESUMO
The transduction efficiency of human bone marrow CD34+ cells with supernatants from the retrovirus producer cell clone PA317/LGSN 16 was only one-fifth of that with supernatants from GP+ envAm12/LGSN 15, even though both producers had similar infection titers on 3T3 cells. PA317/LGSN 16-conditioned medium inhibited the proliferation of the bone marrow CD34+ cells, and this inhibitory effect was partially blocked by anti-transforming growth factor beta antibodies. These studies suggest that cytokine secretion plays a role in the suppression of retrovirus transduction of human CD34+ cells.
