Stem Cell Related Patent Number US6569427
| Title: | Isolation and preservation of fetal and neonatal hematopoietic stem and progenitor cells of the blood | | Inventors: | Boyse, Edward A.; Tucson, AZ, USA
Broxmeyer, Hal E.; Indianapolis, IN, USA
Douglas, Gordon W.; New York, NY, USA | | Summary: | Described herein are methods of providing hematopoietic reconstitution via introduction into the patient of a composition having a cryoprotective agent such as dimethyl sulfoxide and human neonatal or fetal hematopoietic stem or progenitor cells. The invention relates to hematopoietic stem and progenitor cells of neonatal or fetal blood that are cryopreserved, and the therapeutic uses of such stem and progenitor cells upon thawing. Therapeutic applications in immune reconstitution are included, such as for the treatment or prevention of various diseases and disorders such as anemias, malignancies, autoimmune disorders, and various immune dysfunctions and deficiencies. Various embodiments of the invention include fetal or neonatal hematopoietic stem and progenitor cells which contain a heterologous gene sequence which can be used for hematopoietic reconstitution in gene therapy. Further disclosed are methods by which neonatal or fetal blood cells that have been cryopreserved and thawed may be used in autologous reconstitution. | | Abstract: | The present invention relates to hematopoietic stem and progenitor cells of neonatal or fetal blood that are cryopreserved, and the therapeutic uses of such stem and progenitor cells upon thawing. In particular, the present invention relates to the therapeutic use of fetal or neonatal stem cells for hematopoietic (or immune) reconstitution. Hematopoietic reconstitution with the cells of the invention can be valuable in the treatment or prevention of various diseases and disorders such as anemias, malignancies, autoimmune disorders, and various immune dysfunctions and deficiencies. In another embodiment, fetal or neonatal hematopoietic stem and progenitor cells which contain a heterologous gene sequence can be used for hematopoietic reconstitution in gene therapy. In a preferred embodiment of the invention, neonatal or fetal blood cells that have been cryopreserved and thawed can be used for autologous (self) reconstitution. | | US Patent Website: | Click Here for Full Text of Patent | | Title Number: | US6569427 | | Application Number: | US1995000442277 | | Date Filed: | 16/05/2995 | | Date Published: | 27/05/2003 | | Assignee: | PharmaStem Therapeutics, Inc., Del Mar, CA, USA |
