Stem Cell Related Patent Number US6303379

Title:Vivo protein production and delivery system for gene therapy
Inventors:Selden, Richard F; Wellesley, MA, USA
Treco, Douglas; Arlington, MA, USA
Heartlein, Michael W.; Boxborough, MA, USA
Summary:This invention describes transfected primary and secondary somatic cells of vertebrate origin, particularly mammalian origin, transfected with exogenous genetic material (DNA) which encodes a desired (e.g., a therapeutic) product or is itself a desired (e.g., therapeutic) product. Also disclosed are methods by which primary and secondary cells are transfected to include exogenous genetic material, methods of producing clonal cell strains or heterogenous cell strains, methods of gene therapy in which the transfected primary or secondary cells are used, and methods of producing antibodies using the transfected primary or secondary cells. Included are primary and secondary somatic cells, such as fibroblasts, keratinocytes, epithelial cells, endothelial cells, glial cells, neural cells, formed elements of the blood, muscle cells, other somatic cells which can be cultured and somatic cell precursors, which have been transfected with exogenous DNA which is stably integrated into their genomes or is expressed in the cells episomally. The exogenous DNA either encodes a product, such as a translational product (e.g., a protein) or a transcriptional product (e.g., a ribozyme or an anti-sense nucleic acid sequence) which is a therapeutic product or is itself a therapeutic product (e.g., DNA which binds to a cellular regulatory protein or alters gene expression). Such a delivery system is an expansion of related, previous inventions by the same assignee and inventors.
