Patents by Inventor Irina V. Klimanskaya

Irina V. Klimanskaya 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).

  • Patent number: 11739366
    Abstract: Methods are provided for detection of a target cell type within a cell population, and compositions are provided comprising cells and an indicator that indicates the number of cells of the target cell type in the cell population. Examples are provided in which these methods are used to detect human embryonic stem cells within a differentiated cell population with exquisite sensitivity. Differentiated cells produced from embryonic stem cells can be characterized by these methods before transplantation into a recipient, thereby providing further assurance of safety.
    Type: Grant
    Filed: July 25, 2011
    Date of Patent: August 29, 2023
    Assignee: Astellas Institute for Regenerative Medicine
    Inventors: Irina V. Klimanskaya, Roger Gay
  • Patent number: 11422125
    Abstract: This disclosure provides a new phagocytosis assay to test the function of RPE cells and photoreceptor progenitors using a pH sensitive fluorescent label.
    Type: Grant

  • Publication number: 20210308187
    Abstract: This invention relates to methods for improved cell-based therapies for retinal degeneration and for differentiating human embryonic stem cells and human embryo-derived into retinal pigment epithelium (RPE) cells and other retinal progenitor cells.

  • Publication number: 20200405767
    Abstract: This disclosure provides the first description of hESC-derived cells transplanted into human patients. Results are reported for one patient with each of Stargardt's Macular Dystrophy (SMD) and Dry Age-Related Macular Degeneration (AMD). Controlled hESC differentiation resulted in near-100% pure RPE populations. Immediately after surgery, hyperpigmentation was visible at the transplant site in both patients, with subsequent evidence the cells had attached and integrated into the native RPE layer. No signs of inflammation or hyperproliferation were observed. The hESC-derived RPE cells have shown no signs of rejection or tumorigenicity at the time of this report. Visual measurements suggest improvement in both patients.

  • Publication number: 20190062698
    Abstract: This present invention provides novel methods for deriving embryonic stem cells and embryo-derived cells from an embryo without requiring destruction of the embryo. The invention further provides cells and cell lines derived without embryo destruction, and the use of the cells for therapeutic and research purposes. It also relates to novel methods of establishing and storing an autologous stem cell line prior to implantation of an embryo, e.g., in conjunction with reproductive therapies such as IVF.
