Abstract
A genetically modified astrocyte for gene therapy is provided. The genetically modified astrocyte includes one or more stably introduced DNA sequences selected from DNA encoding a selectable marker, DNA encoding a poison pill, and DNA encoding a molecule useful for gene therapy. The genetically modified astrocyte may be produced utilizing plasmids and non-viral transfection methods, as are also provided by the subject invention. Methods for producing and utilizing the genetically modified astrocytes and regulating the engineered products, as well as kits thereof, are further provided.
Claims10
A non-virally genetically modified non-tumorous astrocyte comprising:
- DNA consisting of a first DNA encoding a selectable marker and a second DNA encoding a biologically active molecule;
- wherein expression of the DNA encoding the selectable marker is regulated by the promoter for glial fibrillary acidic protein or by the RSV promoter:
- and wherein expression of the DNA encoding the biologically active molecule is regulated by a regulatory element for controlling expression of said DNA encoding the biologically active molecule, said regulatory element including a regulatable promoter which controls expression in said astrocyte, and
- wherein said first and second DNA, said promoter, and said regulatory element are stably incorporated into the genomic DNA of said astrocyte.
