S. Todd Sorokan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Hypoxia-mediated neurogenesis assay
    Patent number: 6924142
    Abstract: Methods are described for the production of neurons or neuronal progenitor cells. Multipotent neural stem cells are proliferated in the presence of growth factors and erythropoietin which induces the generation of neuronal progenitor cells. The erythropoietin may be exogenously applied to the multipotent neural stem cells, or alternatively, the cells can be subjected to hypoxic insult which induces the cells to express erythropoietin.
    Type: Grant
    Filed: August 31, 2004
    Date of Patent: August 2, 2005
    Assignee: Neuro Spheres Holdings Ltd.
    Inventors: Samuel Weiss, S. Todd Sorokan
