Abstract
Many gene delivery methods have been used to transduce or transfect bone marrow-derived dendritic cells (BMDCs) for genetic engineered DC vaccine research. The present study, for the first time, evaluated the efficiencies of four methods (lipofection, DNA electroporation, recombinant adeno-associated virus type 2 (rAAV2) transduction, and recombinant lentivirus (rLV) transduction) using EGFP as a report gene in the same BMDC culture system. Our data demonstrate that rLV transduction is the most effective method; both lipofection and DNA electroporation transfect BMDCs at lower efficiencies; rAAV2 can hardly transduce BMDCs. Furthermore, our results, for the first time, demonstrate that rLV transduction efficiency on BMDCs can be improved significantly by co-centrifugation and repeated transduction.
