title: [Transduction efficiency of recombinant adeno-associated virus 2 in human umbilical cord blood CD34+ hematopoietic stem/progenitor cells].
abstract: To investigate the transduction efficiency of recombinant adeno-associated virus 2 (rAAV-2) in human umbilical cord blood CD34(+) hematopoietic stem/progenitor cells, the CD34(+) cells sorted by the method of magnetic cell sorting from human cord blood were infected with the rAAV-2 expressing the green fluorescent protein (GFP) gene. After transduction for 19 hours, the expression of GFP was detected under fluorescence microscope. The results showed that 43% CD34(+) cells expressed the GFP gene at a multiplicity of infection of 2 x 10(5). It is concluded that the rAAV-2 can transduce human cord blood CD34(+) hematopoietic stem/progenitor cells efficiently.
