Abstract

Human umbilical cord blood provides an alternative source of hematopoieticcells for purposes of transplantation or ex vivo genetic modification. Theobjective of this study was to evaluate electroporation as a means to introduce foreign genes into human cord blood CD34(+) cells and evaluate gene expression in CD34(+/)CD38(dim) and committed myeloid progenitors (CD33(+), CD11b(+)). CD34(+) cells were cultured in X-VIVO 10 supplemented with thrombopoietin, stem cell factor, and Flt-3 ligand. Electroporation efficiency and cell viability measured by flow cytometry using enhanced green fluorescent protein (EGFP) as a reporter indicated 31% +/- 2% EGFP(+)/CD34(+) efficiency and 77% +/- 3% viability as determined 48 hours post-electroporation. The addition of allogeneic cord blood plasma increased the efficiency to 44% +/- 5% with no effect on viability. Of the total CD34+ cells 48 hours post-electroporation, 20% were CD38(dim)/EGFP(+). CD34(+) cells exposed to interleukin-3, GM-CSF and G-CSF for an additional 11 days differentiated into CD33(+) and CD11b(+) cells, and 9% +/- 3% and 8% +/- 7% were expressing thereporter gene, respectively. We show that electroporation can be used to introduce foreign genes into early hematopoietic stem cells (CD34(+)/CD38(dim)), and that the introduced gene is functionally expressed following expansion into committed myeloid progenitors (CD33(+), CD11b(+)) in response to corresponding cytokines. Further investigation is needed to determine the transgene expression in functional terminal cells derived from the genetically modified CD34(+) cells, such as T cells and dendritic cells.
