  • Publication number: 20190031992
    Abstract: Organs-on-chips are microfluidic devices for culturing living cells in micrometer sized chambers in order to model physiological functions of tissues and organs. Engineered patterning and continuous fluid flow in these devices has allowed culturing of intestinal cells bearing physiologically relevant features and sustained exposure to bacteria while maintaining cellular viability, thereby allowing study of inflammatory bowl diseases. However, existing intestinal cells do not possess all physiologically relevant subtypes, do not possess the repertoire of genetic variations, or allow for study of other important cellular actors such as immune cells. Use of iPSC-derived epithelium, including IBD patient-specific cells, allows for superior disease modeling by capturing the multi-faceted nature of the disease.

  • Publication number: 20180305651
    Abstract: The invention relates to culturing brain endothelial cells, and optionally astrocytes and neurons in a fluidic device under conditions whereby the cells mimic the structure and function of the blood brain barrier. Culture of such cells in a microfluidic device, whether alone or in combination with other cells, drives maturation and/or differentiation further than existing systems.

  • Publication number: 20180017583
    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.

  • Publication number: 20170226478
    Abstract: The invention relates to culturing motor neuron cells together with skeletal muscle cells in a fluidic device under conditions whereby the interaction of these cells mimic the structure and function of the neuromuscular junction (NMJ) providing a NMJ-on-chip. Good viability, formation of myo-fibers and function of skeletal muscle cells on fluidic chips allow for measurements of muscle cell contractions. Embodiments of motor neurons co-cultures with contractile myo-fibers are contemplated for use with modeling diseases affecting NMJ's, e.g. Amyotrophic lateral sclerosis (ALS).

  • Patent number: 9291530
    Abstract: An apparatus and method are disclosed for sampling and analyzing the exhaust gas or liquid from an internal combustion engine or other device that generates a flow of exhaust gas or liquid during use. The apparatus includes a connector that is adapted to be secured adjacent to an aperture formed through an outlet conduit of an engine or other device that generates a flow of exhaust gas or liquid therethrough during use. A conduit communicates with the connector and is adapted to receive and pass therethrough at least a portion of the exhaust gas or liquid from the outlet conduit. A sensor chamber communicates with the conduit and is adapted to receive and pass therethrough at least a portion of the exhaust gas or liquid from the conduit. A one-way valve only allows the exhaust gas or liquid in the sensor chamber to exit therefrom. Lastly, a sensor senses at least one characteristic of the exhaust gas or liquid in the sensor chamber and generates a signal that is representative of such characteristic.
