  • Patent number: 11248212
    Abstract: The present disclosure provides a method of fabricating cell, such as stem cell, arrays on a carrier where the surface energy of the carrier has been modified and patterned so that only areas of low contact angle are wetted by a water based cell solution. The patterned cell solution when applied to the carrier surface then self assembles into a 3 dimensional micro pattern on the carrier that mimics the surface topography of mammalian organs.

  • Publication number: 20210062147
    Abstract: The present disclosure provides a method of manufacturing and differentiating mammalian stem cells, and in one embodiment human induced pluripotent stem cells (iPSc), e.g., manufacturing neuron progenitors, e.g., derived from iPSC, on a large scale by the use of an automated hollow fiber reactor system. In one embodiment, human iPSc that can be differentiated into cardiomyocytes or neuron progenitors are provided. The method comprises seeding a hollow fiber reactor with stem cells such as iPSc, or differentiated iPSc, growing and expanding the seeded cells using appropriate growth factors and nutrients, and harvesting the cells after expansion from the hollow fiber reactor walls, e.g., with the use of an enzyme. The method can produce billions of cells per week from seeding the reactor with a minimum number of starting stem cells or neuron progenitor cells.

  • Publication number: 20210047611
    Abstract: The current disclosure describes a method of fabricating a n×n where n=1 to 100 micro well plate that has a transparent film bottom where the film has embossed on the surface micro structures for the facilitation of cell growth and differentiation in particular cardiomyocyte cells derived from human induced pluripotent stem cells. In one embodiment, the micro well plate has an array of 384 locations molded out of thermoplastic onto which a micro embossed film is laminated to the bottom. The micro embossed features are fabricated such that that when the film is laminated to the plate, e.g., with adhesive or via welding, the embossed microstructures are located within the individual microplate well locations.

  • Publication number: 20180291336
    Abstract: The present invention discloses a high volume manufacturing process for the production and purification of exosomes. In one embodiment, a hollow fiber perfusion reactor is used to expand stem cells. The growth media used from the stem cell expansion is captured, filtered, centrifuged and exosomes isolated from the waste effluent. In one embodiment, stem cells are derived from bone marrow, fat, blood, cord blood and induced pluripotent stem cells are expanded and the exosomes captured from the growth waste effluent. The exosomes can be used as therapeutics and diagnostics for a number of regenerative and chronic diseases.

  • Publication number: 20180289729
    Abstract: The present disclosure provides a combination therapy to treat neurodegenerative diseases. In one embodiment, Alzheimer's disease is treated with an orally administered mitochondria stimulant, neuro protective antioxidant that crosses the blood brain barrier and is supplemented with a drug that promotes hippocampal neurogenesis. The combination therapy of a mitochondria stimulant, a brain available antioxidant and a neurogenesis agonist, may be employed to prevent, inhibit or treat neurodegenerative diseases that have a root cause of inflammation, oxidative stress, followed by free radical biologic macromolecule destruction, and eventually cell death, such as Parkinson's, age related Dementia, Multiple Sclerosis (MS) and Amyotrophic Lateral Sclerosis (ALS).

  • Publication number: 20180224421
    Abstract: The present patent application discloses, among other things, methods and apparatus for a surface microstructured multielectrode array (MEA) for enabling the auto alignment of living cells on exposed electrodes. In one approach the microstructures are fabricated onto the surface of a multielectrode array and attached to a multi well plate such that the metal electrodes are exposed for the attachment of cells to the surface. The microstructure allows for the living cells to self organize into biologically relevant organ mimics onto the electrodes only, which allows electronic electrophysiology monitoting of their behavior when exposed to, e.g., therapeutic substances.
