Non-virally mediated gene transfer into human central nervous system precursor cells.
Lipofectamine-based transfection was used as a method of choice to deliver the bacterial beta-galactosidase gene into human central nervous system (CNS) precursor cells. We achieved a transfection efficiency of 7.4%. beta-Galactosidase expressing cells were shown to display both neuronal and glial phenotypes. We also delivered the temperature sensitive allele of SV40 Large-T antigen and obtained a high level of expression of the immortalizing oncoprotein in the cells. Colonies of Large-T antigen immunoreactive cells were indeed visible 10 days after transfection.
