Stem Cell Related Patent Number US6225122
| Title: | Human spinal cord cell lines and methods of use therefor | | Inventors: | Sah, Dinah W. Y.; San Diego, CA, USA
Li, Ronghao; San Diego, CA, USA | | Summary: | This invention describes methods of preparing conditionally immortalized human spinal cord neural precursor cells. Described herein are methods for transfecting human spinal cord cells plated on a first surface and in a first growth medium that permit proliferation with DNA encoding a selectable marker and an externally regulatable growth-promoting gene, which is followed by a process of selecting the transfected cells on a second surface and in a second growth medium which permit attachment and proliferation, and which thereby produce a conditionally-immortalized human spinal cord neural precursor cell. Also included are therapeutic uses in the prevention and treatment of a variety of spinal cord-related diseases and injuries, in assays for the general study of spinal cord cell development and differentiation, and for producing a conditionally-immortalized human spinal cord neural precursor cell. If such cell lines are clonal, they may also be used to generate neurons, including motor neurons. | | Abstract: | Conditionally-immortalized human spinal cord cell lines are provided. Such cell lines, which may be clonal, may be used to generate neurons, including motoneurons. The cell lines and/or differentiated cells may be used for the development of therapeutic agents to prevent and treat a variety of spinal cord-related diseases and injuries. The cell lines and/or differentiated cells may also be used in assays and for the general study of spinal cord cell development and differentiation. | | US Patent Website: | Click Here for Full Text of Patent | | Title Number: | US6225122 | | Application Number: | US1998000059790 | | Date Filed: | 13/04/1998 | | Date Published: | 01/05/2001 | | Assignee: | Signal Pharmaceuticals, Inc., San Diego, CA, USA |
