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.

Stem cell-based lung-on-chip models

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, C 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.” In some embodiments, epigenetic signatures include (but are not limited to) identifying specific combinations of modifications of chromosomes and specific modifications of DNA.

Organs-on-chips as a platform for epigenetics discovery

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.

Devices, systems and methods for inhibiting invasion and metasases of cancer

A microfluidic device is contemplated comprising an open-top cavity with structural anchors on the vertical wall surfaces that serve to prevent gel shrinkage-induced delamination, a porous membrane (optionally stretchable) positioned in the middle over a microfluidic channel(s). The device is particularly suited to the growth of cells mimicking dermal layers.

Open-top microfluidic device with structural anchors

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. Additionally, these microfluidic &#x201c;organ-on-chips&#x201d; allow identification of cells and cellular derived factors driving disease states in addition to drug testing for reducing inflammation effecting epithelial regions.

In vitro epithelial models comprising lamina propria-derived cells

The present invention relates to microfluidic fluidic devices, methods and systems as microfluidic kidney on-chips, e.g. human Proximal Tubule-Kidney-Chip, Glomerulus (Kidney)-Chip, Collecting Duct (Kidney)-Chip. Devices, methods and systems are described for drug testing including drug transport and renal clearance. Further, such devices, methods and systems are used for determining drug-drug interactions and their effect upon renal transporter functions. Importantly, they may be used for pre-clinical and clinical drug development for treating kidney diseases and for personalized medicine.

Microfluidic proximal tubule kidney-on-chip

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.

Advanced pulmonary models

Devices, systems and methods for inhibiting invasion and metastases of cancer

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.
