BACKGROUND: For our clinical immunogene therapy study for the treatment of renal cell carcinoma (RCC) patients, we had developed a protocol for gene transduction and expansion of human T cells in compliance with good manufacturing practice (GMP) criteria. Critical to our successful clinical-scale transductions of patient T cells was the use of Retronectin in combination with Lifecell X-foldtrade mark cell culture bags. METHODS: In our current study, we evaluated two alternative types of bags for the Retronectin-mediated retroviral transduction of human T cells: the Miltenyi DC-generation bag and the Takara CultiLife Spin bag. RESULTS: In static transductions, but not in spinoculation, the DC-generation bags and CultiLife Spin bags performed as well as Lifecell X-foldtrade mark bags in Retronectin-assisted retroviral transduction of human T cells with respect to transduction efficiency, lymphocyte subset composition and lymphocyte function. However, both types of bags performed less well than Lifecell X-foldtrade mark cell culture bags in terms of cell yield. DISCUSSION: Adjusted numbers of cells at the start of transduction should be used when using the Miltenyi or Takara bags in order to compensate for the lower cell yield following transduction.
