Abstract: Provided herein relates to systems and methods for producing and using a body having a central channel separated by one or more membranes. The membrane(s) are configured to divide the central channel into at least one mesochannel and at least one microchannel. The height of the mesochannel is substantially greater than the height of the microchannel. A gaseous fluid can be applied through the mesochannel while a liquid fluid flowing through the microchannel. The systems and methods described herein can be used for various applications, including, e.g., growth and differentiation of primary cells such as human lung cells, as well as any other cells requiring low shear and/also stratified structures, or simulation of a microenvironment in living tissues and/or organs (to model physiology or disease states, and/or to identify therapeutic agents and/or vaccines). The systems and methods can also permit co-culture with one or more different cell types.

Abstract: An organomimetic device includes a microfluidic device that can be used to culture cells in its microfluidic channels. The organomimetic device can be part of dynamic system that can apply mechanical forces to the cells by modulating the microfluidic device and the flow of fluid through the microfluidic channels. The membrane in the organomimetic device can be modulated mechanically via pneumatic means and/or mechanical means. The organomimetic device can be manufactured by the fabrication of individual components separately, for example, as individual layers that can be subsequently laminated together.

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.

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.

Abstract: The present invention relates to the use of gels for cell cultures, including but not limited to microfluidic devices and transwell devices, for culturing cells, such as organ cells, e.g. airway cells, intestinal cells, etc., and co-culturing cells, (e.g. parenchymal cells and endothelial cells, etc). As one example, the use of gels results in improved lung cell cultures, such as when using transwells and microfluidic devices, (e.g. for culturing healthy airway epithelial cells, culturing diseased airway epithelial cells, e.g., CF epithelial cells that are ciliated). The present invention relates to fluidic devices, methods and systems for use with gel layers within a microfluidic device. In particular, a partial gel layer is disposed within a microchannel of a microfluidic device. For example, a partial gel layer has a thickness ranging between approximately 20-100 ?m. A dilute partial gel layer of less than 100 ?m may be formed from a polymer solution of 0.5 mg/ml.

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.
