Cells used as the target were CD34-enriched human bone marrow stem cells. Retrovirus vectors used were LNL6 and G1Na40, both carrying the Neomycin-resistant (Neo-R) gene as a genetic marker. Transduction efficiency varied from 5.1% to 35.0%, depending on the factors and procedures in the experiments, which cornprised MOI, the duration of exposure of cells to the vectors, and conduct/nonconduct of centrifuge of the cells during the exposure. The most effective gene transduction into CFV-GM was found to be a 48h-liquid culture with growth factors followed by 48h-vector exposure with the spin transduction.}, pages = {311--315}, title = {2) 遺伝子マーキン : ヒト造血幹細への遺伝子導入(シンポジウム 遺伝子治療をめぐる諸問題, 第509回新潟医学会)}, volume = {110}, year = {1996} }
