  • Patent number: 12098352
    Abstract: An in vitro microfluidic “organ-on-chip” device is described herein that mimics the structure and at least one function of specific areas of the epithelial system in vivo. In particular, a stem cell-based Lung-on-Chip is described. This in vitro microfluidic system can be used for modeling differentiation of cells on-chip into lung cells, e.g., a lung (Lung-On-Chip), bronchial (Airway-On-Chip; small-Airway-On-Chip), alveolar sac (Alveolar-On-Chip), etc., for use in modeling disease states of derived tissue, i.e. as healthy, pre-disease and diseased tissues. Additionally, stem cells under differentiation protocols for deriving (producing) differentiated lung cells off-chips may be seeded onto microfluidic devices at any desired point during the in vitro differentiation pathway for further differentiation on-chip or placed on-chip before, during or after terminal differentiation.

  • Publication number: 20240309331
    Abstract: The present invention relates to a combination of microbes, cell culture systems and microfluidic fluidic systems for use in providing a human Intestine On-Chip with optimal intestinal motility. More specifically, in some embodiments, a microfluidic chip containing intestinal epithelial cells co-cultured with intestinal endothelial cells in the presence of bacteria, such as probiotic bacteria, may find use in providing an Intestine-On-Chip for testing intestinal motility function. In some embodiments, an Intestine On-Chip may be used for identifying (testing) therapeutic compounds continuing probiotic microbes or compounds for inducing intestinal motility for use in treating gastrointestinal disorders or diseases related to intestinal function.

  • Publication number: 20240299932
    Abstract: The present invention relates to microfluidic fluidic devices, methods and systems for use in identifying epigenetic signatures in a range of sample types, e.g., cells established on a “chip” (including but not limited to single cell samples, cell populations, cell layers and whole tissues, such as a biopsy), immune cells, cfDNA, exosomes, and the like. More specifically, in some embodiments, a microfluidic chip containing a sample is contacted with a test compound (e.g. DNA altering test compound, an RNA expression altering test compound, etc.) for use in providing a diagnostic epigenetic signature for that type of sample (or cell type) exposed to that specific test compound. In some embodiments, after contact with a test compound, effluent fluids (e.g. fluids exiting the “chip” that contacted the cells) are derived for testing as a “virtual blood draw.

  • Patent number: 11970680
    Abstract: The invention generally relates to a microfluidic platforms or “chips” for testing and understanding cancer, and, more specifically, for understanding the factors that contribute to cancer invading tissues and causing metastases. Tumor cells are grown on microfluidic devices with other non-cancerous tissues under conditions that simulate tumor invasion. The interaction with immune cells can be tested to inhibit this activity by linking a cancer chip to a lymph chip.

  • Publication number: 20240024873
    Abstract: An in vitro microfluidic “organ-on-chip” is described herein that mimics the structure and at least one function of specific areas of the epithelial system in vivo. In particular, a multicellular, layered, microfluidic culture is described, allowing for interactions between lamina propria-derived cells and the associated tissue specific epithelial cells and endothelial cells. This in vitro microfluidic system can be used for modeling inflammatory tissue, e.g., autoimmune disorders involving epithelia and diseases involving epithelial layers. These multicellular, layered microfluidic “organ-on-chip”, e.g. “epithelia-on-chip” further allow for comparisons between types of epithelia tissues, e.g., lung (Lung-On-Chip), bronchial (Airway-On-Chip), skin (Skin-On-Chip), cervix (Cervix-On-Chip), blood brain barrier (BBB-On-Chip), etc., in additional to neurovascular tissue, (Brain-On-Chip), and between different disease states of tissue, i.e. healthy, pre-disease and diseased areas.

  • Publication number: 20230287355
    Abstract: The present invention relates to microfluidic fluidic systems and methods for the in vitro modeling diseases of the lung and small airway. In one embodiment, the invention relates to a system for testing responses of a microfluidic Small Airway-on-Chip infected with one or more infectious agents (e.g. respiratory viruses) as a model of respiratory disease exacerbation (e.g. asthma exacerbation). In one embodiment, this disease model on a microfluidic chip allows for a) the testing of anti-inflammatory and/or anti-viral compounds introduced into the system, as well as b) the monitoring of the participation, recruitment and/or movement of immune cells, including the transmigration of cells. In particular, this system provides, in one embodiment, an in-vitro platform for modeling severe asthma as “Severe Asthma-on-Chip.” In some embodiments, this invention provides a model of viral-induced asthma in humans for use in identifying potentially effective treatments.

  • Patent number: 11150255
    Abstract: Compositions, devices and methods are described for preventing, reducing, controlling or delaying adhesion, adsorption, surface-mediated clot formation, or coagulation in a microfluidic device or chip. In one embodiment, blood (or other fluid with blood components) that contains anticoagulant is introduced into a microfluidic device comprising one or more additive channels containing one or more reagents that will re-activate the native coagulation cascade in the blood that makes contact with it “on-chip” before moving into the experimental region of the chip.
