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+envAml2/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 13 antibodies. These studies suggest thatdoi:10.1128/jvi.68.11.7634-7636.1994 fatcat:dxaiajauijdc5diq4yrpnpn43e
