Patents by Inventor Elizabeth A. Lipke

Elizabeth A. Lipke 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).

  • Publication number: 20220403338
    Abstract: The present invention relates to the production of cell cultures and tissues from undifferentiated pluripotent stem cells using three-dimensional biomimetic materials. The resultant cell cultures or tissues can be used in any of a number of protocols including testing chemicals, compounds, and drugs. Further, the methods and compositions of the present invention further provide viable cell sources and novel cell delivery platforms that allow for replacement of diseased tissue and engraftment of new cardiomyocytes from a readily available in vitro source. The present invention includes novel methods required for the successful production of cell cultures and tissues, systems and components used for the same, and methods of using the resultant cell and tissue compositions.

  • Publication number: 20220125735
    Abstract: The devices, methods, and compositions disclosed herein accomplish robust cell encapsulation in polymer microparticles using a vertically oriented microfluidic device. A hydrophilic polymer precursor solution is flowed into a first inlet channel, which extends inward from an upper surface of the device housing. A hydrophobic fluid is flowed into a second inlet channel, which extends inward from a lower surface of the device housing. The two inlet channels meet at a junction, and an outlet channel extends away from the two inlet channels. When the two inwardly flowing streams meet at the junction, the polymer precursor solution disperses into the hydrophobic fluid. The dispersed precursor droplets are photopolymerized into microparticles as they travel through the outlet channel. The resulting microparticles are highly uniform, and are larger than conventionally formed microparticles. Cells of varying types can be encapsulated with high viability and spatial uniformity.

  • Publication number: 20200222596
    Abstract: The present invention relates to the production of endothelialized matrices and materials from immature endothelial cells using substrates to which particular peptides have been grafted. The resultant substrates can be used to capture and support immature endothelial cells. Further, the methods and compositions of the present invention provide viable cell delivery platforms that allow for production and provision of endothelialized medical devices and implants, including vascular grafts, stents, shunts, and valves, endothelialized surfaces and channels for in vitro testing devices, including microfluidic chips, and materials that support vascularization such as for use in engineered tissues. The present invention includes novel methods required for the successful production of cellularized substrates, systems and components used for the same, and methods of using the resultant cell and tissue compositions.
