Stem Cell Related Patent Number US6355241
| Title: | In vivo production and delivery of erythropoietin | | 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 erythropoietin or an insulinotropin [e.g., derivatives of glucagon-like peptide 1(GLP-1)]. Also disclosed are methods by which primary and secondary cells are transfected to include exogenous genetic material encoding erythropoietin or an insulinotropin, methods of producing clonal cell strains or heterogenous cell strains which express eruthropoietin or an insulinotropin, 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. This invention is a variation of number US6531124, in which such methods of delivery were first introduced. | | Abstract: | The present invention relates to transfected primary and secondary somatic cells of vertebrate origin, particularly mammalian origin, transfected with exogenous genetic material (DNA) which encodes erythropoietin or an insulinotropin [e.g., derivatives of glucagon-like peptide 1(GLP-1)], methods by which primary and secondary cells are transfected to include exogenous genetic material encoding erythropoietin or an insulinotropin, methods of producing clonal cell strains or heterogenous cell strains which express eruthropoietin or an insulinotropin, 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. The present invention includes 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 encoding EPO or an insulinotropin, which is stably integrated into their genomes or is expressed in the cells episomally. | | US Patent Website: | Click Here for Full Text of Patent | | Title Number: | US6355241 | | Application Number: | US1999000420861 | | Date Filed: | 19/10/1999 | | Date Published: | 12/03/2002 | | Assignee: | Transkaryotic Therapies, Inc., Cambridge, MA, USA |
