Latest Patents

One of her latest patents is titled "Protein-induced pluripotent cell technology and uses thereof." This invention describes a method for generating protein-induced pluripotent stem cells by delivering bacterially expressed reprogramming proteins into the nuclei of starting somatic cells. The QQ-protein transduction technique is utilized, which involves repeating several cell reprogramming cycles to create reprogrammed protein-induced pluripotent stem cells. The reprogrammed cells are then moved into a feeder-free medium for expansion, allowing for the generation of homogeneous piPS cells. Additionally, the patent provides details on the piPCS cells formed using this method and their various applications.

Another significant patent is "Method and composition for a protein transduction technology and its applications." This invention outlines a protein transduction method that efficiently delivers exogenous proteins into mammalian cells. The method is capable of targeting different cellular compartments and protects the delivered proteins from degradation by cellular proteases. The composition includes cation reagents, lipids, and enhancers in a carrier. This innovative method can be applied in numerous ways, including the production of large quantities of properly folded, post-translationally modified proteins using mammalian cell machinery. It also enables in-cell fluorescence spectroscopy and imaging, as well as in-cell NMR spectroscopy using living mammalian cells. The method allows for cell biology at atomic resolution, which is both physiologically and pathologically relevant, and facilitates protein therapy to treat human diseases.
